The best way I can describe it is like having flu from the neck down. I’m not ill, no fever, but I am in so much pain. It started 3 days ago with just my arm hurting, then yesterday my back hurt too, today my legs and other arm joined in! I’ve had a hot bath and taken some pain killers. So does this sound like a virus? I haven’t done anything to have pulled muscles or anything like that. I don’t know how long to put up with it and just wait to see if it goes. I’m not really sleeping because the pain keeps waking me. Just wondering if anyone else has had anything like this?
