I have intermittent weakness in my elbows and upper arms. It feels like I have just really overworked the muscles and joints there and that area of my body is just worn out. The sensation comes on any time, even in bed. I can still move my arms, but with some effort. My hands may also shake a little, but not every time. The sensation lasts just a minute or two, once or twice a day.
It sounds as if your pain is more likely a muscular one, and you may need mild muscle relaxant for this pain, but you should consult your go before taking any medicine
