Hi, I'm wondering if anyone else here has experienced this...it's a little hard to describe, so I'm having a difficult time getting answers searching online or even talking to multiple doctors. For many months now, maybe even a year, I have had a drastic reduction in flexibility in my hips. Stretches that used to be doable are now impossible. The best example would be the one where you sit on the floor with your legs bent, the soles of your feet touching, knees pointing out to the side. I can get my feet together, but my knees are still basically straight in the air, and I just can't get them down. Sitting "indian style" is out of the question. Around the same time I noticed the sudden disappearance of flexibility, a sharp pain started occuring in my left hip area during certain movements. The location of the pain is not my outer hip or lower back, it's more toward the front of my leg in the area where the leg and pelvic bone meet. It's not really the inner thigh, it starts in the center of the front of my leg, to about three or four inches out toward my hip. The movements that seem to cause the sudden, sharp pain are twisting motions, such as twisting to get out of the car. I notice it most of the time when exercising. Plie squats are very difficult - I can do them very carefully, but naturally I can't point my toes all the way out to the side due to the flexibility issue. Anyway, it seems to happen any time my body twists to the right while my left leg doesn't. Sometimes all it takes is a very slight movement like this and the pain is very severe! It stops shortly after I get out of that position, and it seems like massaging the area helps or doing a hip flexor/quad stretch. I should add that I have had psoriasis for several years, and the potential for psoriatic or rheumatoid arthritis is certainly there. I've discussed this with my dermatologist as well as an orthopaedic surgeon, and they haven't come up with any diagnosis or a solution. I've been on a psoriasis medication for a year and a half now that has cleared me up almost 100% but the possibility of it causing weird side effects (like joint pain) is not out of the question. The orthopaedic surgeon did an x-ray which showed nothing, and he prescribed a high dose of naproxen, which I took daily for a month with no improvement (anti-inflammatory). I do have to mention that I noticed the problem most when I was doing Pilates workouts, then it eased off some when I changed my routine, and now that I'm a month into the Insanity rotation, it's worse again. Since there are so many experts on anatomy, fitness, injuries, etc. around here, I'm wondering if this description sounds familiar to anyone...at this point, I'd be satisfied to find out if it's a joint problem or a muscle problem. Thanks in advance for any comments!!
