I'm currently awaiting an official diagnosis, seeing specialist next week with blood and urine results. I have 9 of the 11 criteria and had symptoms for quite a few years - recently diagnosed with Hashimoto.
About 4 weeks ago I had my first rash flare on hands, arms, shoulders and few on legs and back... they started as blisters, then raised red rash, then they turned to what looked like bruises and now after 4 weeks it looks like scars. However the blisters are starting again but I have avoided the sun, wear hats etc...... as its my nose, cheeks, chest, hands and arms....... could it be the UV lighting directly above my head at work??
