I had the same problem, only all over my body 5 years ago.
I had to shake my arms repeatedly just to get any feeling back in them.
Go to knowthecause.com. Read about how fungus becomes a mycotoxin in your bloodstream and causes nerve damage. Get on a good probiotic....I prefer Dr O'Hira's 12 plus probiotic. It has saved my life!
When fungus, overgrowth of yeast, parasites take over your gut, which 80% of your immune-system comes from your gut, you have an immune-system that is compromised!
Within 3 days of starving the fungus etc. by what I avoided in my food, (corn, wheat, dairy, pasta etc), I felt like a new person and continue to eat the same today. My immune system is so strong, I have not been sick with a virus, flu, cold, not anything for 5 yrs, praise God! I hope this helps!
