I have some answers. Woo Hoo!
Discoid Lupus (aka skin lupus or cutaneous lupus). Of all the possible diagnosis available under the "collagen vascular" umbrella, this one was the best. The rheumotologist asked me a lot of questions, checked my joints, looked at what is left of my rash (it is barely there now) and said there wasn't a lot he could do for me. I don't have pain. My rash is almost gone. My joints and/or lymph nodes are not swollen. He said to keep using the cream (pretty significant chance the rash will return in the same or another place) and let him know if anything changes.
I am not positive why my regular doctor could not tell me all of that, except maybe it was to ensure a spot with this guy, in case things get worse. They could. But, then again, they may not. So there is no need to borrow trouble.
I am working on getting the entire family back on an eating plan that is healthier for us, including lean meats, more fresh fruits and vegetables and less pre-packaged crap. :-) Less sodium and less MSG. I am also trying to up the amount of exercise I am getting, but it is difficult to spend much time outside when the heat index has been in triple digits for the past week and the one time I took Lola for a walk after dark something bit me, four times.
But this has been an eye opening experience and I do realize that I need to take better care of myself.
I'm not 18 anymore.
