About 6 weeks ago, out of the blue, my knee started hurting. It was sore to bear weight. A few days later, my leg felt "dead". I went to see my GP and she wasn't sure what it could be, prescribed me something for pain then said to go back if no better or gets worse. My ankle and foot are now painful. Leg still the same. Yesterday my opposite arm felt "dead" but painful. Almost as if it has been dislocated. It hasn't. Along with these things, I'm also absolutely exhausted and feel nauseous almost daily. Thinking back, I had a period of two weeks when my legs were sore in Feb. Then they stopped being sore. I'm 43. I know only a Dr can diagnose me but wondered if anyone had experienced anything similar? TIA.
