Regarding this I need to know is there hearing difficulty in the right ear? What type of tinnitus, swishing, or continuous? How long it lasts? Is there any vertigo associated with tinnitus? Is there any discharge or fullness of the right ear? Regarding bursts of light, Which eye? Single eye or both eyes? At the same time of tinnitus or at a different time? Are flashes colored or black or white? Is burning on the back of tongue one-sided or both sided? Is there any redness on the tongue? Is there hoarseness of voice or throat pain? Please answer all these questions.
