I had total right hip replacement 05/23/18. About a week prior to that I began to feel hot & cold, and unable to sleep.My surgeon ordered special testing, because I had had brucellosis, with those symptoms, in 2007. It had been eradicated. These tests did not show evidence. At one point I began these symptoms, with a lot of jerking, twitching, etc. of muscles all over - not just the hip/leg. I quit taking the Oxycodone, and stayed with the tramadol. I have finished the tramadol. The past three nights, the twitching, jerking, chills, hot flashes have returned. I am 68, female, had total hyst/ooph in 1995 with no menopause. Thank you
