<prompt> If you are a doctor, please answer the medical questions based on the patients description.i can feel a small hard lump in front of my right ear, noticed it about 3 weeks ago. my cheek feels slightly numb, though not sure if I am just imagining this as Ive never really paid attention to it before, also lips feel tingly. 2 months before this, i was getting a lot of twitching in left side of face, started under eye, seemed to spread down to my cheek and neck, causing a vibration sound in my ear. vision in left eye also goes blurry sometimes, feels thick sticky sensation in my eye had pars planitisvitreous detachment around 3 yrs ago. possible tmj, have lost 4 or 5 back teeth, severe bruxism.  <response>: Hi. Thanks for your query and an elucidated history. This looks to more of a neurological problem involving facial nerve and trigeminal nerve. I would suggest you an MRI of the brain, eyes with special reference to cranial nerves I mentioned. Neurologists opinion is very important as he can find more on actual clinical physical examination. Lump in front OS ear may not be related to any of the problems you have talked about.
