I'm sorry to hear you're having problems. I too have been having allergic reactions. Got a biopsy of the hives and they ruled out a virus, so it looks like a drug reaction. My face gets really red and itchy too. Plus full body hives. Ugh!
What neurological effects did you have? And what has your doctor switched you to? I'm not officially off of it yet.
No drug yet just keeping off. I have twitches, and shaking from humira. I also had the redness and itching but that seems to be stopping now that I'm off.
