Pressure in head, ears and behind eyes.

Hi I am suffering from severe pressure in head, inside ears and behind eyes for last three months. My right ear rings and feels clogged. I was infected by covid like symptoms 3 months ago but tested negative in rtpcr. After that one day I made fast head movements to relieve stiffness in my head and neck, felt sudden severe shock with heat at left side on back of my head and resulted in mild unconsciousness and vomiting. I consulted with neuro and got mri done but no abnormalities found except mucosal thickening of sinuses due to flu. I got tested my eyes and found +0.5 cylinderical power in left eye and +0.25 in right eye. Now it is more than three months, I have continuous pressure around head, ears and behind eyes. My hb1ac, PBS, d dimer, electrolytes, CBC tests, all were normal except vitamin b12 was 187 and random blood sugar 210 and triglycerides 310. I have also done mri contrast, mri cerebral and neck but nil abnormalities. which doctor should I consulted now?
