Questions about Fibromyalgia and POTS Symptoms

My hands and feet turn a purplish color and get cold very easily, as far as nerve problems I was diagnosed with neuropathy when I was diagnosed with pots. I have tried edibles, smoking and CBD for both neuropathy pain and anxiety but all of those tend to make my pots symptoms worst, but I see lots of people with pots say that it helps them

Also a rheumatologist can diagnose & treat fibromyalgia
