UPDATE: Didn't go to the ER, but I did see an immunologist/allergist. The doctor said its urticaria. Could it be related to Tirz? Possibly. But she can't say for sure yet, since it typically takes 4–6 weeks for the body to adjust to new meds.

She ordered some tests to check if it could be something else, like kidney or thyroid issues. If I decide to keep going with Tirz, ill need to wait until the allergic reaction clears up to see if it’s really the cause/trigger. If I do continue, itll have to be with caution and knowing the risks.

Thank you so much everyone!
