around the fist month of Dec. I begin to have this pain in my upper thigh. Though i must have pulled a muscle, then I pinched the back of my lower thigh,upper calf and developed a LARGE bruised(take plavix) since then I can hardly WALK and so much pain..pain is now in my groin( if i press on my pelvis bone,it's painful) lower abd, lower back and all of the thigh..feels like muscle and bone pain. had an xray of hip(normal) back(lumbar spurring) ultrasound of thigh to check for blood clot(normal).. my skin is tender to touch. I just don't know what can be wrong I am so tired of taking pain pills, (which doesn't kill all the pain) and the pain is so bad it wakes me up at night, the pain also moves up into my left buttocks too. I am 63 and have osteporsis,post cva,DJD, among other things. i stay tired and drained all the time my daughter said i had a low grade fever, has anyone had this experience, and what could this be???
