SMZ-TMP DS and vivian

i was prescribed this drug for kidney and bladder infection. i avoided sunlight ( warning on drug label). my skin began to look thin and dehydrated, tingling sensations. my face became swollen and cheeks exceptionally red, like severe sunburn. it's been over two weeks since i stopped taking this medication and my skin still isn't anywhere back to normal. my face actually became flaky.

i have taken Bactrim in the past with none of the above side effects. how does this drug differ from Bactrim.
