I started having this warming sensation on the back of my leg (upper hamstring area) that feels like warm water is spreading down the back of my leg starting around the bottom of my buttocks and ending around around the middle of my hamstring. There is no pain or discomfort, just not sure what it is. A chiroprator told me to see a neurologist because it may be Multiple Sclerosis or Fibromyalga but I'm just not sure. I'm a pretty health 29 year old male so both don't seem very realistic. Any thoughts out there? Anyone else ever had the same thing?
