Suggest Medication For Weakness In The Feet Followed By Cramps

I am having a series of different issues, it all started with weakness in the feet below the knee, I was getting very little sleep so I went on Pharmaton which helped for a few weeks then came the daily swelling of the ankles. i went to the doctor and was sent to do a female executive blood test which showed no problems. I was then sent to d a venous dopler which showed two perferator on both legs which they said was not functioning at the optimal, I was given the compression stockings to wear I have not had any changes sinces. I can feel the weak legs beneath the stockings. All this has been hapenning over eight months and now I get cramps in the middle of my palm, along my hands, my face, my head, I dont know what next to do
