How long does a hip flexor strain last?
You want a number of weeks for a hip flexor strain, and the answer depends on how severe the strain is.
Timelines for mild versus severe strains
Inspira Health ties healing time to severity.
Mild cases typically heal within two to four weeks, while moderate or severe tears can take several months to heal.
That means two to four weeks for mild cases and several months for moderate or severe tears. No single number of weeks fits every strain.

Why the grade decides the timeline
Mild, moderate and severe decide which timeline applies, and someone has to assign the grade. Be cautious about any flat timeline quoted with no grade attached. The word "typically" also marks a usual range, not a guarantee for your hip.
Asking about your grade
Ask a clinician in Totowa or a nearby town which grade they would give your strain and what timeline they would base on it. Keep the date the pain began so the weeks can be counted. For wider reading, see MedlinePlus on hip injuries and disorders, WebMD's pain management center and Cleveland Clinic's explainer on the hip joint.
Checking a quoted timeline
Healing time is tied to severity, and severity is a grade someone has to assign. When anyone quotes you a timeline, ask which grade it belongs to, and compare it with what Inspira Health lists for mild cases and for moderate or severe tears.
