IMHO, the most important thing to do is find docs that are empathetic to your problems.
A neuro who is a specialist in PN and has the most up-to-date info on meds and treatments. A PCP who understands and will work with you, is open to suggestions from you (and your research), & will coordinate with your neuro on meds and tests.
The second thing to do, is read as much as you can and be as informed as possible about what is happening to you.
We all have burning feet (& zaps, zings, stings, buzzing, squeezing, swelling, etc) at one time or another, .... or constantly - without the right meds. A combination of meds ('cocktail') to relieve your symptoms and pains, usually is the ticket to relief.
The PN specialist/neuro....is your first and moist important step in being able to live a normal life, having this incurable affliction.
