the pain started when I was working out one day and I just assumed that I was sore; however, it has gotten much worse. The pain centers from the outside of my left hip, but goes down to my knee and up to my lower back. I am no longer able to sleep at night, because every position is extremely painful. any position, standing or sitting, that is not painful, soon becomes painful after a couple of minutes. I can't seem to figure out what might be the cause of this pain. any ideas would be great, thank you!!
