sinusitis
"I was prescribed on a Tuesday to take Cefdinir for a sinus infection (alongside a steroid which I only took for a day). Tuesday went fine, I felt better. Wed PM before my fourth dosage, I had intense stomach pain (I can normally handle stomach pain/cramps) and was advised to eat something. Felt better and took my 4th pill. Woke up around 3 am Thursday and I could taste the pill in my mouth (indigestion/reflux). Pushed it off, went to sleep, and woke up an hour later and I thought I was dying on the toilet. Stomach pain, diarrhea & vomiting (at the same time) and this weird finger cramp where I couldn’t move my fingers, along with panic/shallow breathing. This lasted off and on for almost two hours (mostly diarrhea) and I was too scared to finish the RX."
