Sounds like it could be an ACL Injure! I suggest seeing an Orthopedist.
Gymdandee provided good advice. See a professional ASAP.
Hey man, sounds similar to some of the things I have going on. The older I get, the more my hip pops. For me, I think "no pain no problem".
If the issue is getting to you, a proper diagnosis might be in order. I'd imagine that it could be any number of things... most likely nothing serious. If it were more of a dire circumstance, you'd be on top of it now rather than down the road, probably stopping further damage.
I'm 46. I played a lot of baseball as a kid. I worked in the bar business for about 20 years and had been in numerous bar room altercations. Both my shoulders pop, my hip pops, my neck and back sometimes pop.... Sometimes at first there is a tinge of pain, but it is almost always followed by some relief. I was told by a doctor that I "ain't a spring chicken" anymore.
Same doctor told me, if there is no pain, if full movement isn't a problem... leave it alone until there is an issue. Hope that helps.... see a doc.
Thanks Brice. I am (was) a baseball guy too. Good to hear that it isn't too big of a deal if there is no pain. There is none at all. I will see a doctor eventually.
You may have mild degeneration of the joints like osteoarthritis. You don't feel pain with mild degeneration.
Your doctor would be able to give you the correct diagnosis.
If you are overweight it does help to lose, but it is not a cure.
I'm 6'1" 180lbs so I'm not overweight but I could be in better shape. I work on the computer all day every day. Could that have caused this?
