Thank you Taml. I still haven't seen my diagnosing doctor. Although she confirmed my SFN diagnosis by phone, she still has me testing for underlying neurological disease. I'm doing a Neuropathy panel this week. I do not know what that tests for. What I want to know is if tht chest pain I've been feeling is related to SFN. My Neurologist said it might be related as SFN. I've read here in other threads that chest pain can manifest with SFN but it may be due to anxiety. What I'm feeling doesn't feel like anxiety though. Happens when I'm cool and calm as a cucumber.
