About a year and a half ago, I experienced something similar with a node on the right preocciptal side of neck. I began experiencing the fevers, sweats, weight
loss, tinnitus, and floaters. I was in the ER three times and admitted twice with ZERO outcome of a diagnosis other than unknown. They ran a variety of various bloodwork for autoimmune and viral tests like Epstein-Barr, Julien-Barait, lupus, Lyme, Brucellosis, etc. all were negative.
