Sulfamethoxazole and white as a ghost

I was prescribed this med in DS form for a lingering sinus infection that I had for over a month and a half. The first day was ok except when I went to bed I started feeling a headache coming on. I figured it was just because my sinuses were infected and dry. The 2nd day after only the first pill of the day, DS (RX 2x daily) I went about my morning workout and pretty much felt ok; just a little tired. However, when I got home, I started feeling chills and then hot, then thats when the horrendous MIGRAINE hit me. From there my eyes were swollen, blood shot, I was white as a ghost in the face, my head and ears started closing up, I was painfully fatigued all over like I had the flu. Now into day 2 evening, my throat is starting to swell and hurt. Even after taking something that usually works for my occasional stubborn headache, it for the first time ever, did NOT work. I still have the migraine now. I did call Kaiser today. They said they knew these could be possible side effects. I just don't know how, with so many issues/complaints about this drug from such a broad spectrum of people and all OVER THE WORLD that they would not halt the release of anymore of this drug to anyone! In fact I was reading a report, I believe from the UK where they have banned this drug. There are so many other options that yes come with side effects but NO THING close to what Ive seen here. I know ,but isn't it sad that the drug companies will never let that happen here. I have taken different types of antibiotics and this is the WORST! I expect I will be making a trip to the ER at the rate this keeps going.
