My husband has a skin infection which he was taking tablets prescribed by the hospital where they diagnosed it. He took them for quite a few months, but they didn't seem to have any effect. Long term use of them can cause other problems, (but I can't remember what, possibly liver damage) It is affecting his back, has spread and almost covers his back now and gets very itchy at times. He also has a patch near his groin which is also spreading. He uses clotrimazole cream to try and control the itching, sometimes it helps. I should add he has also been diagnosed diabetic recently and takes omeprazole as he now also gets bad acid. I am thinking that this needs to be tackled from the inside, but need advice on how and what to use.
