Thanks everyone for your responses...I did have tylenol and benedryl before my infusion....Yes, the benedryl definately makes me very groggy and sleepy...I came home and slept 3 hrs and was pretty much normal...The evening after, my legs got achy and feeling as if I had been standing all day...That went away over the night, I woke up and felt fine...I went a whole week with no signs of any reaction, then I was so sore!!! I kept trying to put pieces together to figure out what was causing it...In some way I feel it was returning to work after having a 1 1/2 week off, but I usually dont get like that...Maybe some sorness, but not like I experienced this time...Even the joint in the left side of my jaw was sore...I blamed that on me jabbing the back of my throat with a sharp potato chip...LOL...It was just to weird...Anyway, I called the dr. and they talked to a few of the other dr since mine wasn't there and they recommended me not getting my next infusion...I don't know what will be next...Any ideas?? I don't feel I have a severe case of UC, just can't get the meds to work unless its pred. What will be next for me?
