Talk to Gynecologist on Burning Sensation On Peeing

I delivered vaginally on 6th February. My stitches were hurting a lot so my mother suggested me to use few drops of pyodine in warm water and sprinkle them on vaginal stitches to heel them fast. Now, the problem is I feel burning sensation too down there which wasn’t there before and have difficulty passing urine too. I am currently using mycitracin on stitches. Is there anything I can do to remove that burning sensation?
