I been through many infections and antibotics in the past 2 months. I started off with a uti which the doc prescribed me with smz/tmp 800 - 160 mg. By the first few days I been taken it, I have had server dirrariha, very painful headache that last all day everyday until the effect wore of for another pill. Very nauseated and upset stomach. I bought yogert, probotics and nothing work so I talk to the doctor to switch me to a different one which if nitrofurantion mono hyd mocro. All the same symptoms including lost of appetite but the headaches was finally gone. So I pushed through it till all them were gone. Few day later felt fine but the nausea, dirrariha was still there followed by mucus in stool. Turns out it gave me c-diff. Yay me...so more rounds of antibotic metronidazole 500 mg and the same damn pill smz/tmp ds 800-160 mg both be taken at the same time. I ate hoping to be ok but boom as soon as I took them a hour later nausea, throwing up, headaches, watery yellow stool with no solid part at all, just pores like water, I thought I poisoned myself so had to be rushed the the er at 9pm had to be hooked to a iv, run a few test and all that could say was to switch meds again that I prob had a allergic reaction to them and to be put on bed rest for a few. I am so worried the new one might cause the same effects and I don't want that. I need to work but also don't want to be there rushing to the bathroom every few mins feeling like I'm going to vomit or diarrhea v.v any advice at all, I am losing weight and dyhidracted can eat without feeling sick idk what to do anymore.
