Hi. I am a 42 year old dance instructor. Last night during warm-ups I was stretching in my left split. I usually stay about 8 inches of the ground. However, last night while holding the position (and supporting my weight with my hands) something "gave" in my hip and I slipped about 3-4 inches lower. It was pretty painful. As I came out of the position it felt as though my Left hip "jerked" or "popped" back into place. I never heard a "pop" sound it was just as if something shifted out of place. As the night went on the pain became more and more intense, and by about 3 hours later I could put no weight on it at all without pain. Today it is very painful to do anything at all that stretches my left leg. Sitting (especially on the toilet) and walking (not as painful going down stairs) hurts a ton. Trying to stand from a sitting position is impossible unless I use something to pull myself up (like a table). The pain stems from the inner front of my left leg right at the bend and on my butt right where I sit. It is radiating down the back of my leg to the back of my knee. My whole left leg from the hip down feels affected somehow. I usually have a pretty high pain tolerance and this has me concerned because at times I have been in tears today. I have had many work outs over the years that left me feeling sore the next day but this is a whole different category. Any ideas?
