i suffered a major left sided hemiparesis in july 04 i started suffering from violent muscle spasms in my left quads muscles?
your condition is unilatteral which suggests neural problem but the severty indicate electolyte level problems as well. i suggest doing mri scan over your lumber vertebra increasing your calcium potassium intake and try burger circulatory exercise (elevate your leg while going ankle pump 15 times then drop leg below bed level for 30 sec other leg must be flexed though out the exercise repeat 3 times twice a day )if this helps then you will need doplar on your leg good luck
