SMZ-TMP DS and sunburn

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.

I was prescribed smz tmp for a minor kidney infection. I took the drug for 5 days and stopped because my side (the skin) began to itch and it felt like a severe burning on my skin - like sunburn.
It has been 6 days since I last took the medication. I know that it can take a couple of weeks for it to get out of my system, but is there anything I can take to alleviate these side effects?
