I have got 3 crowns placed after RCT, and I have severe pain inside the mouth around the caps and swollen gums. To this the doctor prescribed to have medicines for 5 days and said it's normal. But the two medicines Flozen Plus and Ornida 500 are making me feel really uncomfortable. I am feeling weak, pukish, have fever, sweating alot and not even able to eat, sometimes feeling cold too. Should I stop taking the medicines or is it normal to have such side effects? Am losing weight too, worried ofcourse. Pulse rate is not normal, bp is fluctuating and I feel suffocated.
