I’m currently being treated for a Lyme-like issue after something bit the back of my neck in June. I wonder if it was something like this. We live in the NH woods with lots of deer, bears etc. I scratched it off without seeing what it was and within two weeks got stiffness in my neck, then in a month my shoulders and finally it spread to shoulders elbows knees and hands. After 3 weeks on antibiotics it’s mostly gone except for my hands and a little bit in my shoulders. My hands have it the worst.
