I Am Having Large Blisters In My Mouth. Is It Due To Bactrim I Had?

August 4th 2014 I presented hematuria and bladder and urethra pain. After an ER visit I was put on Pyridium and bactrim DS, both I have had before, for previous UTIs that seem. to occur every 5-6 years. But shortly after
starting that bactrim, my mouth erupted into large multple canker sores. I finshed the bactrim /pryridium course , the infection appeared to have cleared up.

August 27th I began to have discomfort again in my urethra and bladder while voiding, and mild spasms in both areas when not voiding. yesterday I started back up on pyridium and bactrim, last night I developed large blisters again in my mouth, my lips are swollen up again, too, and I'm not experiencing much relief at all from bladder/ urethral discomort. Should I discontinue the bactrim, and go see a female urology MD ?
