I have been getting severe cramps back of thighs, leg falling asleep when sitting for a little while along with foot swelling ony left leg?

Discuss with your MD: All of these symptoms may be local musculo-skeletal problems but you need to talk to your doctor. Cramps could be an electrolyte disorder. One sided swelling could be venous insufficiency but it could be phlebitis. The leg falling asleep is most likely a compression of a nerve while you are asleep. However, you have a number of leg questions that requires someone seeing you personally.

A physical exam: Is in order. You may want to see your oby-gyn. An ultrasound may be a good idea to make sure you have no fibroids. An ultrasound of the leg to make sure no clot is not a bad idea as well, though suspicion can be decided based on clinical exam. Cramps can also be caused by dehydration or viitamin deficiencies i.E magnesium, potassium. Leg sleepng may be compression neuropathy from way you sit.
