Do u have insurance? If so do you need a referral? If possible it is a good idea to see a neurologist. While your waiting see your GP and have some blood work ordered. If you have not already had them done recently they should order B12, mag, B6, and Vit D. That's what I can think of right now but others may have more suggestions.

Also, if you use a lot of OTC NSAIDS you may want to have your renal function tested. Only if you use a lot.

Your symptoms do sound like small fiber neuropathy but try not to worry too much. Have all the testing done first. It may be something that can be taken care of easily likeB 12 deficiency. Plus worrying makes the symptoms worse.

Keep us posted. Hopeful
