For longer range treatment of an injury that is not healing on its own, you should consider diet, essential oils, and cleanses. You should start juicing fruits with pectins in them and also consider doing liver, gallbladder, and kidney flushes so your body can begin healing itself. Have you tried essential oils? If I had your condition, I would rinse my ear daily with apple cider vinegar then rub in a combination of tea tree oil, lavender oil, and grapefruit seed extract. Find the right combination of diet, cleanses, and essential oils and you might just cure your condition and be a lot more healthy for it.
