Sounds a lot like Morgellons, which is associated with Lyme. I believe the first line of tests when Morgellons is suspected is just testing for tick-borne infections. There are several threads on this forum about it if you use the search bar. Joni Mitchell has it, which is how a lot of people have heard of it, but it's a poorly-understood and most don't know about it.
Also look into mast cell activation issues and nerve issues.
My partner (who does not have Lyme) gets something similar in the winter on his shins, but it helps him a great deal to wear only natural fabrics and to supplement vitamin D.
