In need of some advice or information. I have been on cimzia injections for 5 months now and have been doing very well with them, but I have experienced a significant amount of weight gain. Also, my joint pain and GI cramps are back significantly. I am convinced the weight is from injections but doctors are telling me no. Has anyone else experienced weight gain from their meds?? I have been dieting and exercising and still gaining. I need reassurance that it's not just me.
