Stubborn person symptoms and conditions

I was prescribed Doxy 100mg 2x a day for a sinus/eye infection 2 years ago after sinus surgery. It upset my stomach so bad but my doctor said to keep taking it because the stomach upset was less problem then this infection. I also got a yeast infection. Didn't have to deal with the sun because it was winter in the midwest. My stomach never returned to normal. Now I am labeled having IBSD. I have very frequent diahrhea on & off. It seems go into remission every now & then. I have had an upper & lower GI too. Nothing was found. Now 2 years later I get another sinus/eye infection. Doc gives me again. I forgot this was the same drug I had 2 years ago until I called my old pharmacy and had them check my records. This time I only took one pill after eating. I took it at 6:30pm. At 1am I woke up with a burning pain in my chest. I was sweating so badly. I got up and ate some soda crackers. I didn't feel nauseaus, just burning pain like heartburn. I finally got back to sleep at 3:30am. Woke up at 11am.

I remembered what the doc said 2 years ago and decided to take another dose. With food of course. About 4 hours later I was in the bathroom bent over in pain with the runs severely. I called the doctor. Being it was Saturday and after hours I got the oncall doctor who wasn't very sympathetic. All her heard was CHEST pain and ordered me to go to the hospital ER. I argued abit with him and he just yelled back "Go to the ER now." Being the stubborn person I am, I did not go. But I did not take another dose. I called the pharmacy the next day and told them what happened. They said it was definitly a drug reaction. I am going to call my doctor tomorrow and demand a different med. This stuff should be banned.
