Looking for Relief from Guillain Barrie Syndrome Symptoms

I suffered Guillain Barrie Syndrome (GBS) in 2017 after surgery in a dirty hospital. Than spent 45 days in another hospital (5 days in ICU and 10 days in a coma. I still have tingling in my hands and feet. Sometimes, my feet are worst than usual and hurt to walk. I know the Doctor said that it could take 5 years to go away, if I was lucky. It’s been more than 5 years now. I have heard some people get over it. I keep looking for something that would help me improve (other than exercise and diet, which hasn’t helped). I keep checking for new medical improvements, but haven’t seen any. QUESTION: Has anybody found something that has helped improve the feelings in hands and feet. Please let me know. Thank you in advance. “Rollin”
