I have been experiencing numbness in my feet and hands for years, however as of the last month I am experiencing severe burning in my feet and hands. Now I am having numbness in my cheek and chin. I do have problems in my lower back and see a chiropractor regular with no relief. I do occasionally have Sciatic pain in my but cheeks when I walk. My blood sugar is around 89. I am worried because both hands feet and face are affected. The pain in my feet radiates to above my knees. I am a 50 yr old semi fit man.
