I have horrible burning in my feet! Have been diagnosed w/ SFN, however just by talking w/ a Neurologist. My circulation test was fine. He based it on paperwork I had filled out & the pain I was experiencing. I want to get a punch biopsy to make sure this is the correct diagnosis. This is SERIOUS & so painful. So did anyone start out like me & the burning pain has traveled up your body to different areas. I’ve read where burning is in the head as well??? Scared to death.
