So, without a big shock to the system (cholera, hot weather marathon, diet consisting only of Pabst Blue Ribbon) or an underlying renal or endocrine disease, which are fortunately rare if you don't count iatrogenesis, electrolytes probably aren't the problem. What you have described so far, joint or muscle aches that move around and aren't related to exercise, most often turn out to be caused by that large and ever-expanding category of disease called "I don't know"("idiopathic" if you want to charge for the diagnosis). But sometimes they are symptoms of autoimmune, infectious, neurological, etc. problems that can be treated. Mr. Peak is right, it's worth having this looked into a bit.

Muscle soreness and stiffness are two different things. I believe muscle stiffness is due to a certain amino acid buildup (titin?)...

Not addressing the OP's concern really since he has some issues without exercising, but just saying.

of course you could have pain from bone jamming into muscle, nerve impingement, muscle tear, all sorts of things. i have no clue
