I had a very itchy ear and kept scratching, leaving the outer ear sore and a bit raw. I put sudacrem on it and I think some has gone inside. It feels blocked, a bit like a blocked nose and I can't hear anything in that ear. Do I have to go to the GP? Or can I buy something from Boots to clear it myself? It would take a couple of weeks to get an appointment and it's driving me mad. Any advice would be appreciated. Thank you.
