I am 66 years old and diabetic but diabetes under control. I have to get up in the night as I have pain in my legs and calf area (muscle pain). I have to stand up in comfortable position until the pain goes out and finally go for natures call (urinate). These cramps I have been facing almost every night. Now I have pain in my left leg (thigh area). Doctor says-stiff muscles. Take vitamin E. Pls advise. FYI do to hard work on ship I sleep only for 6 hrs/day.
