Hi, Welcome to the NeuroTalk Support Groups. Sorry it's pretty quite here lately but hopefully others in a similar situation will come forward and post to you.

I'm fortunate that I didn't get covid at all but I do have PN from another cause.

I'm not sure what country you're in but you mentioned going to Thailand so if you're Australian then I would suggest you check into some of the Long Covid / ME CFS (Post Viral Syndromes) clinics that are around in most States here now.
.
There's quite a bit of scientific literature coming out as well.
e.g.,

Long COVID: major findings, mechanisms and recommendations
from Nature Reviews Microbiology


Peripheral Neuropathy Evaluations of Patients With Prolonged Long COVID
from Neurology, Neuroimmunology & Neuroinflammation

I'm sorry that I don't have any real answers for you but I'd really try to get involved with a Long Covid /ME CFS clinic if you can.

Just curious if you had any slight symptoms prior to getting the virus but the virus made it all way worse?

take care,
Lara
