I have the weirdest thing that sounds like I'm totally neurotic. Try this: take your first 2 fingers and poke on yourself shoulders to wrists, firmly, as if trying to get your own attention. Each place I poke myself it hurts. Obviously I'm not going to do this often, but if someone pokes me I tell them it hurts and they do not believe me. Does anyone Else have this ache all over if pocked?
It can be Rheumatism, also a condition called Fibroymalgia. I have tried this and I do not hurt one bit when touched. Fibromyalgia and Rhumatism are muscle, joint and bone disorders, but what you describe can be caused by Thyroid, kidney or even bladder problems. I would strongly suggest seeing a doctor for this “ache all over if poked” .
