My fiance had his left leg amputated about 12-13 years ago. Reacently he is experiencing severe cramps in the inside of his thigh so bad he has to get up. They are becoming more and more of a problem.  He is also having exscruciating cramps in the stump. He had 10 surgeries for blockages over a 20 year period before the amputatin.  Could thee nes cramps be caused by new blockages??
