Hi @markgventnor, welcome to the forum. It’s interesting that you posted about a rash as I have a small place on my ankle that has not generated much interest from any of my assorted “ist” physicians. I haven’t seen a dermatologist yet, but I did have my hem/onc doc and PCP take a look at it. The consensus was that it was a reaction to a bug bite.
It’s frustrating not to get answers and since it’s been six weeks since it emerged, complete with swelling, tenderness and itching, I’m guessing that by the time the dermatologist actually sees me I will have adapted to this new normal.
At any rate, there are skin conditions related to MGUS (thus MGDS) which should be looked into. I suggest not doing a deep dive into Dr. Google and talk to your hem/onc doc once you get in the room. Maybe they can expedite your appointment since you are symptomatic.
Best of luck. Let us know what you find out.

Patty
