How long does a hip flexor strain last?

What the recovery estimates mean

There are two different milestones here: symptoms settling and being ready for your usual activity.

For a mild injury, the first may happen within a week or two. AAOS advises avoiding the activity that caused the injury for approximately 10 to 14 days in many cases, while noting that severe strains need longer. Treat that range as an estimate. Cleveland Clinic, AAOS

More involved injuries can take months. In a 2018 study of athletes with groin pain and MRI abnormalities involving the iliopsoas, one of the hip flexors, average return to play was:

• 8.6 weeks for athletes with muscle strain findings.
• 20.1 weeks for athletes with peritendinitis findings, involving tissue around the tendon.

Recovery times varied widely within both groups. These were athletes with a particular set of symptoms and imaging findings, so the numbers aren’t a personal forecast for everyone with pain at the front of the hip. Yamamoto et al., 2018

Why include them? Because “a couple of weeks” can become an expectation that every injury is measured against. This study documents a much wider range.

Are you sure it’s a hip flexor strain?

Pain location alone cannot identify the injured tissue. A clinician may need to distinguish a strain from another problem, including a stress fracture or an avulsion fracture, where a forceful pull separates a fragment of bone. AAOS

That matters if you’ve been stretching a presumed strain for weeks and nothing is changing. Before you search for a more aggressive exercise, check whether the original assumption was right. Some symptoms need assessment sooner.

When to seek prompt medical assessment

• Seek prompt medical care if you cannot walk or bear weight, or have severe pain, major swelling, extensive bruising or a visible bulge or deformity. A sudden pop followed by marked weakness or difficulty lifting the leg also warrants assessment. Cleveland Clinic, MedlinePlus
• Pain after a fall, collision or other forceful event needs prompt assessment, especially if walking is difficult. Don’t assume it is a muscle strain. MedlinePlus: hip pain
• Persistent deep groin or hip pain, pain at night, or pain that worsens with impact or weight bearing deserves medical evaluation. A stress fracture or a hip joint problem can cause pain in the same area. AAOS: hip strains, AAOS: stress fractures
• Fever, redness or warmth around the hip, especially if you feel generally unwell, needs urgent assessment. These symptoms should not be managed as a routine strain. MedlinePlus: hip pain
• Numbness, progressive weakness, severe back pain or pain radiating below the hip needs medical assessment for possible nerve or spinal involvement. NHS: sciatica, NHS: back pain
• New calf swelling needs immediate medical attention for a possible blood clot. NHS: deep vein thrombosis

When to seek emergency care

Call emergency services for chest pain or shortness of breath, especially when either occurs with leg swelling. These can be symptoms of a pulmonary embolism. NHS: pulmonary embolism

Seek emergency care for back or radiating leg pain with symptoms in both legs, loss of sensation around your genitals or anus, or changes in bladder or bowel control. NHS: sciatica, NHS: back pain

When improvement has stalled

If symptoms haven’t meaningfully improved after a few weeks of treatment, contact a clinician. MedlinePlus specifically recommends follow up at that point. Repeated episodes also deserve assessment. MedlinePlus

An assessment does not automatically mean you need a scan. Examination helps guide the decision; imaging may be useful when a clinician needs to rule out a fracture or investigate another suspected injury. AAOS

What to do while it recovers

For an uncomplicated strain, recovery commonly involves modifying aggravating activity, then restoring movement and strength. The sequence below is general education. It cannot determine your diagnosis or give you an individual exercise prescription. AAOS

1. Stop repeatedly provoking the pain

If running caused the injury and running still hurts, repeatedly checking whether you can run is working against the advice to rest from the provoking activity. AAOS recommends avoiding that activity during the early recovery period and backing down if pain returns when you resume. AAOS

You can use that principle to make a concrete change: pause the painful workout instead of attempting it every other day. Ask a clinician which alternatives fit your symptoms if you’re unsure what movement is reasonable.

Ice may help with early pain and swelling. MedlinePlus advises wrapping it in a cloth and using it for up to 20 minutes at a time. Use it for symptom relief; the guidance does not show that ice shortens healing time. MedlinePlus

2. Restore comfortable movement before forcing range

A sore hip can make stretching feel like the obvious answer. But forcing a painful stretch can aggravate symptoms. AAOS describes gentle stretching followed by strengthening as symptoms permit; MedlinePlus advises avoiding exercises that cause pain. AAOS, MedlinePlus

The goal is to regain usable movement. You don’t need to prove how far you can push into a stretch.

A physical therapist can help choose exercises and adjust them to your limitations. That becomes especially useful when you’re unsure whether a movement is helping or repeatedly aggravating the same spot. MedlinePlus

3. Build toward the activity you actually want back

Your exercise progression needs to account for what you intend to do. In their review of return to sport after hip injury, Draovitch, Maschi and Hettler recommend matching return testing to the demands of your sport. Draovitch, Maschi and Hettler, 2012

For example, if your goal is recreational running, a useful conversation with your PT is: “What should I be able to do before trying an easy run, and what response means I should stop?” If your goal is a physical job, describe the actual work. Climbing stairs while carrying equipment deserves a more specific discussion than “I want to be active.”

Research specifically on rehabilitation for isolated hip flexor strains is limited. This review covers hip injuries broadly, so it cannot supply one exercise schedule for every strain. Your exercise selection and progression need to account for your symptoms and activity demands. Draovitch, Maschi and Hettler, 2012

4. Pay attention to what happens after activity

Progression needs feedback. AAOS advises reducing activity if pain returns. The review by Draovitch, Maschi and Hettler also says the return decision should account for your symptoms and how well you can perform the task you need to resume. AAOS, Draovitch, Maschi and Hettler, 2012

A short note can make that feedback easier to use:

• What activity did you do, and for how long?
• Did it hurt or change the way you moved?
• How did your hip feel afterward and the following morning?

Bring those observations to your clinician or PT. “I walked for 15 minutes and started limping near the end” gives them more to work with than “it’s still sore.”

No single pain score in this article can clear you to progress.

When can you run or work out again?

AAOS recommends returning once strength and flexibility have returned to their previous levels. If more strenuous activity brings pain back, reduce the activity and allow more recovery time. AAOS

A comfortable walk asks much less of your hip than a run. Even if you’ve reached the recovery date you expected, you may still need to assess whether you can perform the movements your sport demands without pain or compensating for the injury. Return testing may include strength and range of motion alongside those tasks. Draovitch, Maschi and Hettler, 2012

If you have a race or match coming up, say so during your assessment. Give your clinician the distance, intensity and other demands so you can discuss what returning would involve.

Where GoodMetal fits

GoodMetal’s programs are built by licensed physical therapists with 10+ years of experience each. They designed the structure every plan follows: which exercises are included, how weekly sessions are arranged, and how the phases progress.

That structure gives you a pace to follow, with guidance on how the work changes across phases and when to hold back. You can see what the plan calls for each week without assembling a routine from separate exercise searches. GoodMetal includes a large library of guided exercise videos.

These general templates cannot replace individualized medical care. An app cannot determine whether your pain is a strain or clear you to return to sport.

If your symptoms are severe or the diagnosis is uncertain, start with an assessment. If a clinician has confirmed an uncomplicated strain and recommended exercise, you can ask whether a structured program fits your recovery needs.
