Macrobid and stomach pain

I think I'm going to die... I took pill #6 (100mg) which translates to 3 days and I think I'm going to die... I just got back from ER with liver/stomach pains... even though I repeatedly let the nurses know I was taking Macrobid and Xatral, the doctors never EVER got wind of it and treated me as if I had an indigestion. After taking my 6th pill, my throat is swelling up like mad, I have funny heart beats, strong stomach pain, funny tingling pulses in the fingers, and I feel like I'm going to pass out, I'm out of breath, and I feel so dizzy and lightheaded and I'm afraid of passing out for fear I will stop breathing when I do...

I had intense stomach pain and diarrhea after one dose. Called Dr. on call, she said it was a separate virus from my UTI, and to continue doses. After last dose 2 days ago, I broke out in terrible hives that itch uncontrollably, and looks like I have a chemical burn behind my ears and scalp. I thought it was bedbugs from a hotel, until my eye swelled up. Went to Dr. today, she said it might be allergic reaction to the Macrobid, but was weird that it came after all doses. I have also been sleeping for the past two days with NO energy...

I have been taking Macrobid for approximately four days. I have had increased headaches that won't go away with normal medication dose. I also have had horrible gas...in addition to stomach pain. I have have had increased urination, having to pee constantly. I have been getting up about four times at night, which is worse than before I went to the doctor. I wasn't sure if this was the UTI or the medication? Saw someone else's posting that they had increased urination too. I'll keep taking b/c I don't want the UTI to continue but the med is not fun.
