I have spots mostly on my legs and arms, that break out and itch. I don't scratch much... or for very long. After the itching subsides, the area gets purple dots on it, like a hickey almost. (Odd but hopefully descriptive enough). FINALLY the area bruises, and it's always super tender. It goes away in about a week to a week and a half.
I'm sorry you're feeling this way, but it's really important to speak with a healthcare professional to discuss your options. A doctor can guide you on the best approach for your condition and provide the support and treatment you need. Please reach out to a medical professional for proper advice and care.
