weak bones and tight muscles won't relax

This past week my muscles in my entire body became tight, somewhat like after you work out with weights and get a "pumped" feeling. I wake up with tight, stiff fingers and calves, which makes sense since I use those muscles a lot. (Whatever gets used seems to get tighter afterwards.) The fingers and calves started mildly months ago, but now it has spread to the whole body and gotten worse. It's almost like the muscles can't get rid of a chemical that makes them relax.


I recently found out I had weak bones and very low blood Vitamin D. I started taking Calcium and D supplements around the time this got worse.

Does this sound like anything familiar? Virus? Autoimmune? Vitamin allergy? I cannot find anything anywhere that sounds like it, and it is very scary. Thank you
