Thank you for sharing your story, @trish1 I have been checked and am negative for Lymes. While I do have some of the more common SFN symptoms like tingling in my hands and toes, for me, it's really been the autonomic dysfunction that's been quite challenging such as dizziness, chest pain, heart rate and BP fluctuations. In this regard, I've not been able to find the appropriate physician or care team to put their collective hats together and come up with a coordinated treatment plan. My cardiologist says "well, your heart is fine so go talk to your neurologist." That's not very helpful.
