I was perscribed sulphameth for a mild urinary tract infection 2 aday for three days...It was the worst experience EVER..while at work I started to feel a little off not right ..what manifested was a huge panic attack uncontrollable shaking extremely cold then hot continual itching in the groin and my body was sapped of all energy I didnt feel like I could move a finger...Icouldnt sleep properly I just lay there like a lump of lead....I thought I was going mad until I realised it was highly coincidental to taking sulphameth...Ilooked up some sites and found this one...I am so relieved to know I wasnt mad
