Basically, To start with about a week and a half ago i had a burning sensation when i pee’d, then lead to a few spots of blood and a constant urge to pee! My urine was cloudy and smelt a little. I went to the Dr’s and he said i have Cystitis and he prescribed me Trimethoprim and i have been taking this for 2 days now! The burning sensation has almost completely gone now, and just when i think it’s getting better, i have been producing a lot of white/yellowy mucus/discharge ... which surely isn’t normal? And just today it has been itchy, red and swollen! Helpppppp! Is it just a side effect of what i have been prescribed or is it a reaction to it? Is it just part of the Cystitis or is it an STD? pleaaaasee help!
