Hi there, I'm new to this forum and just wanted to ask a question. I was diagnosed with Hashimoto's last July and am now on levothyroxine with bloods in normal range. About 3 days ago I woke up with a painful bruise on my upper arm which is purple/red and looks almost blotchy under the skin. I don't remember hurting myself but I am quite clumsy and do bruise easily. When I woke up it was really sore, almost muscular pain so I'm sure I'd remember hurting it. Should I be worried about this? The doc said I should look out for symptoms of other auto-immune diseases and read this could be a symptom of lupus? I should also say that I still feel shattered and fuzzy too. Thanks in advance.
