Hi Doctor, I have been having dizziness and ear pain frequently for the past 10 days. The pain is less frequent but only on the left side. I feel like it is wet and blocked on the inside. Also, close to where I have the ear ache, I have had some ulcers in the back of my throat for 4 months which have not been healing. When I have a cold or sore throat, the ulcers and my throat hurt really badly on the left side. Today, when touching my ulcers, I also felt a lump in the back of my throat (again on the left side) very close to the ulcer. It seems about pea sized and hurts when I press it. The ENT tested me for allergies and hearing test, but everything seems mostly ok. Should I change my doctor? Please help.
