I had my 4th infusion about 10 days ago and had a really bad reaction. I had just started the infusion when I felt uncomfortable cramping in my upper left arm then the pressure in my chest started. The nursing staff noticed right away and called the doctor who ordered them to stop the infusion. Just as they gave me a shot of benadryl to help control the bad reaction, I started to shake and pass out. Since that time, I've had terrible headaches and a very painful stiff neck. So painful that I haven't been able to sleep. It has been 10 days and I'm still experiencing the stiff painful neck and terrible headaches. I won't ever take this again. I'd rather suffer with the affects of RA than with these horrible headaches.
