all you need to, noone should have to deal with PAIN and side effects from blocks. I have never had any side effects from mine, but I do know you can. Hopefully, the side effects will soon be gone and you'll feel better.
I am concerned about your mouth, if your Dr. did not know about BMS did he say he would research it? Hope it clears up soon!! But if it doesn't and your side effects linger talk to your Dr. about your feelings about having another block. Carose
