Hello, My dad has an injured ear canal and we had been to an ENT specialist for its treatment and have confirmed that the drum is totally fine. The ear canal wall is injured due to piercing of an ear bud. There appears to be dried blood clot in the canal which is blocking the air to reach the drum. My dad, however, has suffered from acute ischaemic stroke and is facing severe anxiety issues. He is getting inconsolable due to irritation caused by the clot. The only ENT specialist in the town is not available most of the time. In this case, will it be safe to clean the blood with hydrogen peroxide? I was thinking of using the liquid by dropping a few drops in the affected ear, leaving it for a few seconds and then letting it flow out. It would be of great help if you assist me on this ASAP.
