Eczema Treatment Care

around October 7th we all went swimming in an overchlorinated hot tub and my sister in law and I both got urinary tract infection’s and my mother in law supposedly got a yeast infection. However, she is currently on Diflucan for that and Lorazapam to help her sleep and there is no relief, her symptoms are redness and rawness on the outside of the vagina and it just hurts as well as she has been complaining of abdominal pain she has no discharge and no odor. She is also very exhausted. These meds aren’t working and she has contacted several doctors (one who didn’t even look) Is there anything else she can try that isn’t going to have all these side effects and does anyone think it could be irritant dermatitis? Help!!!
