Does anyone else get this? From time to time the entire right side of my body aches. I don't know why. It'll start off with my knee (which I've injured in the past) hurting and then the pain starts to radiate down to my ankle and up to my hip, before my right arm and shoulder starts to ache. It isn't agonising pain, just a general ache, and it mainly happens at night and is gone by the next day. But it's very odd!
