Fifities symptoms and conditions

I am a 52 year old male from South Florida. Two years ago my Dr prescribed Lipitor. I started to feel weakness in my legs after mowing the lawn but I dismissed it as just being worn out from the summer heat and humidity. About six months ago the little toe on my left foot became numb and it spread to my other toes. I get continuous spasms in my left big toe and now the toes on my right foot are becoming numb. When I sleep at night I am continuously being woken with leg cramps in my feet, calfs and thighs. My feet feel heavy, my legs feel weak. There are times that I just lose my balance. I have a physical job and when I get home I don't want to do anything. I am going to see a neurologist on 3/31 to see what he thinks. My biggest fear is that I now have permanent damage. I have not read any articles about individuals having a full recovery after stopping the medication.
