When I was about 4 I discovered that if I lay on my back and rotated my right knee out toward the ground it would make a loud clicking noise. Felt that the femur was popping out of the hip socket a little. Fairly sedentary... Joined the gym a couple years back.
Lying on my back trying to do leg raises it wouldn't get very far off the ground. Sometimes a bit of a stabby pain in the front of the femur / socket but mostly just felt weak. Can do these okay now - but pretty weak at them (don't practice very often truth be told).
External rotation (e.g., bad girl machine, cobblers pose) after a lot of work - if I concentrate on pulling the femur into the socket while I do the movement I can usually avoid the clicking. Not as smooth a movement as the other leg, though.
Unweighted sumo squats are really hard to stand up - clicky, some dull pain at the anterior of the right femur / front of the hip socket. Very weak. Closer stance squats feel better - but still not 100%. Hip flexors are tight - and I've been working hard on gently stretching them out. Right is tighter than left. Feels like I'm having some problems recruiting my right glute because my right flexor is so tight. When I am recruiting my glute okay sometimes it feels like my femur is jamming painfully against the front of the hip socket, though. After a bit of that I get a tendonitisy / inflammed feeling in the joint / flexor - not sure where precisely.
Get a similar tendonitisy / inflammed feeling in the joint / flexor when walking sometimes. I think recruiting my glute actually makes this worse. Not sure if this makes any sense at all... Hurts to raise my right leg just to walk when it feels like that (usually when walking after a heavy squat session). Feels like the anterior part of the femur is jamming against the socket painfuly.
I've tried googling to figure this out... Caught between just keeping on with the exercises (which do seem to be helping) as maybe it is just that what is loose needs to be tight and vice versa since my way of dealing with this was previously to avoid those movements. Though it was worth mentioning, though, in case someone knows what this might be (e.g., I worry a little that maybe there is a tear or adhesion or something to the cartilage in the joint). Hip replacements are frequent for women in my fathers side of the family. If I need an MRI then that will take some persuading... But if it sounds likely that I have something that could be fixed I'd really really really like to get it fixed.
