I'm a newcomer here, aged 83. Earlier this year had facet joint injections to deal with severe left side lower back pain - pretty successful. About 2 weeks ago developed general ache across lower back, together with sleepiness, and put this down to a viral infection, though had no other symptoms. Had two days in bed, afterwards ache still present but not too bad, sleepiness gone. However, last evening developed quite severe pain on the right side of upper buttocks. Have never had right side pain before. Currently staying in bed, since standing too painful. Taking Cocodamol, wwhich gives some relief but makes me dopey. Ibuprofen doesn't seem to help. Any ideas most welcome.
