About 10 months ago, I attempted the Smolov squat program. A couple weeks in, my left hip flexor region was really giving me trouble and forced me to drop the program. For the following few months, I was in a lot of pain (even from walking or lying down with hips slightly flexed) and my left hip popped all the time.
At the time, I also had really poor glute activation, bad hip mobility, and significant anterior pelvic tilt. It seemed likely that the cause of my problems was femoral anterior glide (although I never had a real diagnosis).
After taking some time off, I focused on strengthening my glutes and hamstrings, doing lots of hip mobility, static stretching my tight hip flexors and quads, and soft tissue work. Maybe five or six months after the injury, I felt like I was completely fine.
However, starting about a week ago, my hip started to bother me pretty significantly again - it’s been popping all the time in various planes, and it hurts even in unweighted hip flexion positions (not quite as bad as original injury).
The thing that’s puzzling is that I was taking a deload week when my hip started really bothering me. I hadn’t squatted in about a week or deadlifted in about five days.
I think some of the possible factors include the fact that I’ve been nursing a back injury which I made worse with light deadlifts the previous week, and the fact that I was under an unusually high level of stress.
It seemed like taking time off, doing lots of soft tissue work, hip mobility drills, strengthening my glutes and hamstrings, and static stretching my hip flexors and rectus femoris really did the trick the first time I injured my hip.
However, it doesn’t really seem like any of those are an issue right now, but my hip is bothering me nonetheless. Do any of you guys have any advice or even experience with recurring injuries that come back unexpectedly?
