Thanks for contacting HCm with your medical concerns You recently being having a problem with a red rash, possibly fungal infection, in your groin and in the folds of your arms. The first thing I recommend is that you stop using the Augmentin and the triamcinolone ointment. The Augmentin is an antibiotics and will kill off all the good bacteria and your skin allowing the fungal infection to grow unchecked. normal bacteria on our skin helps protect from overgrowth of fungus. Also Augmentin can cause more allergies and the recent rash with itching maybe allergy to Augmentin. The second thing is that the triamcinolone is a steroid and it will also help the fungus grow. Steroids reduce immune response again allowing for the fungus to grow. Third keep the areas where you have a rash as dry as possible. Fungus likes to grow in areas that are warm dark and moist. Fourth continue diflucan and nystatin powder or spray. These are antifungal medication and will help control the infection Hope I answered your question.
