I have been on an antibiotic medicine for an ear

Patient: I have been on an antibiotic medicine for an ear infection and sinus infection for about 5 days now, and I have also been taking a high dose of alieve that was prescribed to me for my back and hip. Recently after taking the antibiotic I started having this feeling of being hungry in my upper abdomen but it was a sharp pain and it came in waves. I have had this for about 2 days now, going on 3. I woke up this morning, got ready, and had to use the bathroom before I went, and when I got up from using the bathroom I blacked out. I have been home today and I have already had diarrhea twice, the pain in my upper abdomen is still there and it’s starting to hurt my chest and the pain goes all the way around to my shoulders. Everytime I eat it helps with the pain for about 30 mins then it starts hurting again. It is keeping me from sleeping at night and I don’t know what to do. Please help!
