I've been on hrt patches since October ish. I increased to 75mg four months when some symptoms began to return. Over the past two days my hips and knees have started to hurt again. Today I'm in bed in agony with them. I know I need to get up and move to see if it helps but instead I'm laid in bed after a horrendous nights (no) sleep feeling sorry for myself. Why now? I'm into my second box of estradot (first week) so I don't know what has made it come back.
