question: On May 18, I suddenly developed chills and a fever of 102. Fever continued, though getting lower, for 3 days. The illness left as quickly as it came. On May 22, I woke up with severe pain in my left thigh, groin area. I thought I d done something while asleep and caused a groin pull. I stayed off my feet as much as possible for the next 3-4 days. Took flexeril and pain meds. It started feeling better, but on May 27 it started hurting more. On May 28, my right leg, same area as the left, started hurting. It s so painful today I can barely walk. Occasionally when taking a step, feels like my leg wants to let go . I m a female, 68 yo, have fibromyalgia.
