<s>[INST] 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 planitis/vitreous detachment around 3 yrs ago). possible tmj, have lost 4 or 5 back teeth, severe bruxism. [/INST] 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. </s>
