My right ear is blocked since last night. Tried opening it with a little massage, or yawning or swallowing or burping gesture but nothing seems to be helping. Can I use some OTC ear drops or medicine which can help open it. There is no pain at all but my ear tend to accumulate more ear wax. It was itchy since a few days. I have a young child to take care of so cannot visit hospital facility immediately. Please help.
