Recently had a mrsa infection in groin area, red bumps. treated with bactrim (sulfamethoxazole and trimethoprim) 2 weeks ago now i have vaginal burning, no sores. could it still be mrsa?

Not necessarily: Symptoms of a yeast infection may include: burning, redness & itching of the vulva; burning with urination & vaginal intercourse & a clumpy, white, vaginal discharge with no odor. Sometimes the discharge isn’t apparent. Use of antibiotics can sometimes lead to yeast infections. Let your doctor know about your symptoms.
