What the Hell Just Happened?

It was early afternoon, I think, when the pains started bothering me. My right hand was visibly swollen, redding appearing in the meaty part of the thumb and also where the hand joins the wrist. (To be honest, my thumb had been bothering me for some weeks.)

Then, both my knees began to hurt. This is the first time I can recall that happening. By Sunday morning I was nearly incapacitated. I took some Oxycodone I had saved from a previous illness. It only helped a little. Every step I took was agony. My knees were both swollen with red patches that were warm to the touch.

I tried to get comfortable in my LayZboy, where I spent most of the day watching TV. I started to feel chills, so I covered myself. Later I felt hot, and felt my sweat soaking through a little bit. I took my temperature: 99.8. It would get as high as 100.5. I definitely felt ill, in addition to the pain that was making me miserable.

I had seen a rheumatologist last year who diagnosed me as having palindromic rheumatism. Is this what I was experiencing?
