What is this weird rash on my arm? No pain, not itchy, haven't scratched it. Noticed it when I took my jumper off. Nerve pain in lower arm.
Wondering what this might be? It appeared randomly on my right arm, along with nerve pain (which I experience regularly but don't know the cause of) in the lower forearm which feels like air on burned skin, however on the rash itself I don't have any pain or itching. I'm used to having rashes (urticaria and demographic) and allergies, but never anything like this. Doesn't fade under glass. I also started recently bruising more than normal.
Haven't done anything out of the ordinary today
I have food intolerances but not allergies.
Medications - Mounjaro.
Other symptoms in past few days - headaches/pain behind eyes, extreme tiredness.
