Strained & Pulled Muscles
A muscle does not tear because it was unlucky. It tears because it was asked for more than it had. Dr. Andrew Allen treats the strain and finds out why it happened, so the same hamstring stops going out every spring.
Over 20 years of experience · Wheat Ridge, Arvada, Lakewood, Golden & West DenverIt is always the same muscle, isn’t it
You felt the grab. You limped it off. You iced it, rested two weeks, felt fine, went back out, and re-tore it inside of a month. Or you have simply accepted that your left hamstring is just how you are now. Here is the thing nobody tells you about strains: the tissue heals, but scar tissue is not muscle, and the reason it failed in the first place is still sitting right there waiting. Rest is not a treatment. It is a pause. At Lakeside Spine & Injury Center, the point is to make this the last time.
How muscle strains actually show up
Strains have a grade and a character. What you felt at the moment of injury tells us a great deal:
The grab
A sudden catch mid-stride or mid-lift that stopped you cold. Usually hamstring, calf, groin, or quad. You knew immediately.
The pop
An audible or felt pop with immediate weakness. Higher grade, worth evaluating promptly rather than waiting it out.
Bruising a few days later
Discoloration tracking downward with gravity. That is blood from the tear finding its way to the surface, and it tells us about severity.
Tight, not torn
A muscle that feels perpetually on the edge of grabbing. Chronically overloaded tissue often feels tight precisely because it is not strong enough.
Fine walking, fails sprinting
Everyday life is painless. Speed, hills, or load reproduce it instantly. That is a capacity problem showing itself only at the top end.
The knot that formed after
A dense, ropy spot that appeared during healing. That is scar tissue and guarding, and it is a re-injury risk if left alone.
It keeps coming back
Same muscle, same season, third year running. The strongest predictor of a strain is a previous strain, and that is not fate, it is unfinished business.
The other side now hurts
You compensated for months and the good leg got the bill. Extremely common and completely predictable.
Deep glute or groin ache
Strains here are notoriously stubborn and notoriously misdiagnosed, often confused with hip or back problems.
The tear is the event. It is not the cause.
Muscles fail at the moment demand exceeds capacity. Every strain has a story about why capacity was low or demand was high that day. These are the root causes Dr. Allen is actively ruling in or out:
A joint above or below that stopped moving
This is the big one. If your hip will not extend, your hamstring finishes the stride. If your ankle will not dorsiflex, your calf absorbs what the ankle should have. The muscle that tears is frequently the one covering for a joint that quit. See hip pain.
A muscle doing someone else’s job
Weak glutes mean the hamstring becomes the primary hip extensor. It is not built for that, and it will eventually resign. Hamstring strains are very often a glute problem.
Prior scar tissue
Healed muscle is not new muscle. Scar tissue is stiffer and less compliant, so load concentrates right at the junction between old scar and healthy tissue. That is exactly where re-tears happen.
Eccentric weakness
Most strains happen while the muscle is lengthening under load, not shortening. If you have never trained the lengthening part, you have never trained the part that fails.
Load spike
You went from zero to a lot. First warm weekend of spring, first ski day, first game of the season. Tissue adapts on a timeline, and that timeline does not care about the weather.
Fatigue late in the session
Most strains happen in the last third of an activity. Tired muscles absorb force worse, and coordination degrades before you notice it has.
Nerve tension
A nerve that is irritated upstream can change how a muscle fires and how it tolerates lengthening. Recurrent hamstring trouble with a history of back pain deserves a look at the back. See lower back pain and sciatica.
Asymmetry
One side that is meaningfully weaker or stiffer than the other is a strain looking for a date on the calendar. It is measurable, which means it is fixable.
Cold starts
Colorado mornings are genuinely cold, and cold tissue is less compliant. Shoveling at 6 a.m. and first-chair skiing are both cold-start activities.
Returning to sport too early
Pain-free is not the same as ready. The gap between when it stops hurting and when it can handle load is where almost every re-injury lives.
How Dr. Allen figures out what is actually wrong
You get evaluated and treated on day one. Not a clipboard and a handshake and a see-you-next-week.
We reconstruct the moment
What you were doing, what phase of the movement, how far into the session, whether you had done it before, and whether you felt a grab or a pop. The mechanism narrows the diagnosis before anyone touches anything.
We grade the strain
Palpation, resisted testing, and length testing to establish how much tissue is actually involved. A grade one and a grade three have very different timelines, and you deserve to know which one you have.
We look upstream and downstream
The joint above and the joint below. Hamstring means checking the hip and the low back. Calf means checking the ankle. This is the step that determines whether it happens again.
We test the whole chain
Strength, control, and symmetry side to side. Numbers matter here, because your sense of readiness and your tissue’s readiness are frequently different things.
We connect it to your life
Your training load, your ramp-up, your sport, your season. The cause is usually sitting in your calendar.
You get treated the same day, and you get a return plan
You leave your first visit having actually been treated, and knowing what has to be true before you go back out. If your case needs imaging or a referral, Dr. Allen will say so directly.
Colorado is hard on muscle
We would not live anywhere else. But the Front Range lifestyle has a signature, and after twenty years Dr. Allen can usually guess your hobby from your movement pattern.
The first warm weekend
Sixty-five degrees in March and the entire Front Range goes outside at once. We can practically schedule the following Monday in advance.
Opening day at the resort
Eight months off, then six hours of hard skiing on cold quads. Quad and groin strains are a November tradition on I-70.
Snow shoveling
Maximum load, cold tissue, before coffee, with no warm-up. It is a strain protocol, and every storm delivers.
Fourteener descents
Descending is eccentric loading for hours, which is the exact condition muscles tear under. Quads and calves take the brunt.
Rec league season
Softball, soccer, and kickball leagues full of people who sit at a desk all week and then sprint to first base. The hamstring never sees it coming.
Clear Creek Trail volume jumps
Runners and cyclists adding mileage faster than tissue adapts. The trail is too nice, and that is genuinely part of the problem.
Gardening season
Wheat Ridge earned the Carnation City name honestly. Eight hours of hauling and kneeling after a winter indoors is a load spike with a shovel.
Altitude and dehydration
Dry, thin air means most people here are running low without noticing. Poorly hydrated tissue and hard efforts do not mix well.
Climbing and bouldering
Dynamic loading at end range, plus falls onto pads. Golden and the gym scene keep groin and shoulder strains coming.
How we treat muscle strains
The muscle will heal on its own. Whether it heals into something that holds up is the part we actually influence. Dr. Allen builds care around what your evaluation found.
Soft tissue therapy
Hands-on work to influence how scar tissue lays down and to restore glide between tissue layers, so the healed muscle behaves like muscle instead of a splint.
Dry needling
Thin monofilament needles into the guarding and trigger points around the injury, including the deep tissue hands cannot reach. Often what breaks a stubborn recovery loose.
Chiropractic adjustments
Restoring the joint above or below that made the muscle work overtime in the first place. This is the part that changes whether it happens again.
Cupping therapy
Decompression-based soft tissue work that may help circulation and tissue mobility around a healing strain.
Progressive loading
The actual treatment. Muscle heals stronger when it is loaded appropriately during healing, with the eccentric work that most rehab skips entirely.
Return-to-activity criteria
Not a date on a calendar. Specific things your leg has to be able to do before you go back out, tested rather than guessed.
Muscle strain FAQ
Should I ice it?
Ice is fine for comfort in the first day or two, and it is not going to ruin anything. Just know that inflammation is part of how tissue repairs itself, so aggressively shutting it down for weeks is not the win people think it is. Gentle movement usually does more for a strain than a bag of peas.
How long until I can play again?
It depends on the grade and the muscle. A minor strain can be weeks, a significant one considerably longer. The more useful answer is that return should be decided by what your leg can do, not by how many days have passed. Dr. Allen will give you criteria, not just a date.
Why do I keep re-tearing the same hamstring?
Because the reason it tore is still there. Almost always it is scar tissue at the old site, eccentric weakness that was never trained, and a hip or back that never got addressed. Rest resolves the pain and resolves none of that, which is exactly why it keeps happening.
Should I stretch a strained muscle?
Not aggressively, and not early. Pulling on healing tissue does not help it. What helps is graded loading, which is a different thing entirely and needs to be matched to where you are in healing.
Is it a strain or something worse?
Sudden pop with immediate weakness, an inability to bear weight, or a visible deformity all warrant prompt evaluation rather than a wait-and-see. Dr. Allen screens for the presentations that need imaging or a referral and will tell you straight.
Will I have to come three times a week forever?
No. There are no long-term contracts and no forced treatment plans here. The goal is to get you back out and keep you there.
Can I just rest it?
You can, and the pain will go away. That is not the same as the muscle being ready. The gap between those two things is where nearly every re-injury we treat was born.
Do you take my insurance?
Coverage questions are best answered directly. Call or text (303) 351-0744, or check the FAQ.
Make this the last time.
You can rest it and hope, or you can find out why it failed. Get a real evaluation from a doctor with twenty years of hands, and go back out with something that holds.
