Hello, both of my thighs bother me ( quads). i cannot walk long distances without stopping to rest.. what ?

Need to be seen: If the patttern is walk a set distance, thighs hurt and sort of "cramp" and it is relieved by rest only to happen again at the approximate same distance, you could have a vascualr condition called IC or intermittant claudication. This should be seen by a physician to be ruled out, or in. If you smoke, it is time to quit!

Pain in thighs: It could be coming from your back, although less likely to have both sides at the same time. Do you have circulatory problems?
