Do you do barbell shrugs? I have found that EVERY time, for whatever reason, Barbell shrugs will literally paralyze me in pain from the waist down for the next few days. Then again, I have SERIOUS issues with my hips. After I got out of the Air Force (I was a heavy aircraft mechanic/"Crew Chief"), and after 2 complete hip overhaul surgeries, I discovered there are just some things I cannot do anymore. I cannot run, do barbell shrugs (though Cable Shrugs are just fine), squat, or deadlift (but somehow leg-press is fine). If you do go to the doctor, prepare for several years worth of going around the pole. I've been playing this game for 4 years, living on Oxycontin. The best they're gonna do is check you for Piriformis Syndrome, check for FAI, MRI w/ Contrast to look for Labral tears, and possibly an arthroscopic investigation to look around inside your hip to see what's going on. They may even give you a Brain MRI to see if the pain is all in your head (thanks Military Docs)!
Here's one thing you can do to really get an idea of the possibility of a structural problem: When you jump straight up, look at your feet when you land. What kind of angle do your feet form with an imaginary line extending straight from your legs away from your body? People that have a large degree of femoral retroversion tend to have a great deal of stress put on their hip sockets, as well as the labrum (which is a suction cup of thousands of nerves in the hips that form a connection with the ball of your femur). The reason I ask is because a lot of exercises say to have your feet pointed forward, but that doesn't take into account someone with a high degree of femoral retroversion. For me, I have to have my feet at a 45 degree angle, because AT THE FEMUR/Hip, my leg is straight ahead (just like a normal person with their feet pointed forward). Had I pointed my feet forward, I would be destroying my hips, which would cause a great deal of pain, and probably another torn labrum. Just a thought.
