I have been going through a very stressful time lately (my husband left me suddenly for another woman), and I developed a urticarial rash during a pseudoflare. However, it didn't go away within a couple days, it stayed for over six weeks. It would pop up every morning and then migrate to a different location. My dermatologist says it's chronic urticaria and it's likely autoimmune, but she doesn't think it's related to MS (likely both the pseudoflare and rash were secondary to stress). Does anyone else get this? She said that she's seen it in people who have anti-thyroid antibodies or lupus, so I'm starting to get nervous that I have more than just MS since Graves and lupus also run in my family.
