I read about
Lymphoma being misdiagnosed as IIH, which they later learned that
Lymphoma cells had infiltrated the optic nerves. That is incredibly rare, and I've only read of 4 confirmed cases of that actually happening. I just thought it was so weird that I was diagnosed with IIH, all while dealing with these swollen nodes, night sweats & weight loss. But the kicker is, it can also be tied to my autoimmune puzzle as well.
I, unfortunately, always think cancer when something pops up.
