I feel as something (like a little hard vain) is growing inside my lips (left joint of lips). I am also facing persistent problem of hoarseness since last four months. By profession Im an assistant professor and deliver lectures in long session (up to 6 hours). I have consulted many doctors (3 ENT, 1 neurologist, 1 cancer specialist, 1 dentist). All say that i don't have any serious problem. But I'm feeling numbness at left side of my head and face specially my left ear. They advised me to take voice rest. I did it for a couple of months but could not observe any remarkable recovery. They recommend some medicines and I'm regularly taking the medicines. My ENT said that numbness is due to my left wisdom tooth. But, I don't feel any pain in wisdom tooth, even it neither is decayed nor have a cavity. My dentist says numbness is not due to my wisdom tooth. Neurologist says (After MRI and CT Scan) that I'm not having any tumor that may cause the problem. But problem is there. I'm feeling serious numbness, my left ear is swelled and red, my voice is too much hoarse and I feel too much dizziness specially in mornings. Please help me and advise me what to do.
