Sounds like Lyme disease along with co infections to me. Unfortunately, the tests are not very reliable and finding a Lyme literate doc is next to impossible. Oh, and less than 50% get that bullseye rash that could be a giveaway to diagnosis.
No rashes or anything else unusual externally.
Check out acam.org for American College for Advancement of Medicine professionals. Also check for functional medicine practitioners. I had an alternative nurse practitioner treat me for c.diff and several other co-infections. It took about 6 months to get it sorted out. Ended up using ozone therapy, which cleared my lymph nodes within 2 hrs of the 1st session.
