Hi, I understand your query. The vaginal rash you have can be allergic( ointments/ cosmatics/ drugs/ ? mesh ), infective , due to dryness of vaginal skin or some thyroid or diabetic problem. Blood work like DLC( for eosinophillia in allergic rash), Thyroid function test, blood sugar testing & deep vaginal swab testing would help in diagnosis. Allergy to mesh is not common, still it can be detected by blood test & treated with medicines/ removed if needful under expert guidance. You should start the investigations after a physical check up followed by investigations & specific treatment thereafter. Thanks.
