I am 48 years old. I have arthritis my doctor have detected no cholesterol or sugar in my blood. My left arm gets numb when i go to sleep; my right leg hurts and the pain is very intense. I cannot go to the bathroom in the middle of the night because both of my legs have no stregnth to hold me. I would like to know of there is a possibility that there might be a illness that only happens at night or what should i do because this only happens when i go to sleep at night and there is sunshine everything goes back to normal. please help me? :'(
