 [ Symptoms ] can taking baths cause vaginal sores  a week ago me and my boyfriend had sex for the first time i was a virgin that weekend i was exposed to the flu and was prescribed tamiflu a few days later i thought that i had a yeast infection so i got medicine for it now i have sores on my vagina i have been taking baths lately and sitting in the tub for a little while my mom said she thinks it could be from me baths or the tamiflu can these things cause sores [ Disease ] hi your doctor put you on a course of these tablets they need to be taken every day till you have finished them along with the lotion means your hitting the rash is from both sides so just keep taken the tablets and apply the lotion if its not gone just go back to your doctor good luck
