Hi, I Have Two Bald Spots That Appeared On My

Hi, I have two bald spots that appeared on my head overnight - totally bald, looks like a razor was taken to my head almost (not possible). One is the size of a quarter, the other is the size of two quarters together side by side. I am not on chemo, but do have chronic auto-immune hepatitis, fibromyalgia, gallstones, thyroid issues, back problems, and migraines. Any ideas?
Thank you for any suggestions. Much appreciated.
