What could be causing this?

For the past couple of days my muscles have been sore. My right shoulder, arm, and hand were so stiff and sore earlier that I couldn't type. I've been so fatigued that even when I wake up after 10 hours of sleep, I'm fatigued. I'm only 20. What could be causing this? Thanks.

My mom went through the same feelings. Her arms even went numb after sleeping through the night. I suggest chiropractic treatment. I don't know your location so I can't advocate a specific physician but basically the spine controls the brain stem and that controls all sensory movements. A few vertebrae out of place and you could be on a very painful road. Good luck.

I've attached a diagram and explanation chart. Hope I was helpful.
