Hi @maryflorida, I thought I would jump in and offer some information I've found that may be helpful. A rheumatologist diagnosed my polymyalgia rheumatica (PMR) and a neurologist diagnosed my small fiber peripheral neuropathy.

What is a Rheumatologist?: https://www.rheumatology.org/I-Am-A/Patient-Caregiver/Health-Care-Team/What-is-a-Rheumatologist
What is a neurologist?: https://www.medicalnewstoday.com/articles/326717#about

And something that really jumped out at me -- What Our Colleagues Should Know: Neurologists & Rheumatologists Must Communicate:

You mentioned in your first post that your rheumatologist prescribed the Gabapentin and that made you sick and then they prescribed Lyrica and that sent you to the ER. It might be helpful to write down a list of all your symptoms and maybe keep a daily log of your pain levels along with any questions you have for the rheumatologist. One question I would have for the rheumatologist or neurologist for any drug that is prescribed - how does this drug work to treat my symptoms?

Can you update us on how your appointment goes with the rheumatologist in June?
