For Dinner I Had A Ham Sandwich With Mayo And

for dinner i had a ham sandwich with mayo and drank part of a can of root beer from a can after a while my right lower lip began to swell a little,,,I recently had 3 implants removed because of infection on the other side of my mouth and cannot chew on that side until the gums heal...I took one benadryl and it seems to of helped some...I have 5 pins in my ankle and have neuropathic pain so i take gabrepathin 300 mgs 3 times a day,,,the ankle was hurting earlier so i took a tylenol # 3 with two 500 mgs of tylenol..what is the problem?
