I have been suffering from a kind of imbalance problem for more than two years. Consulted ent, neuro doctors. But no cure Everyday after 9am I feel this imbalance while standing and heavy  on just above eyes No issues while sitting or walking This feel reduces after lunch time and again crops up by 5pm until dinner Really peculiar. Don't know whom to consult. Please help Took neuro limb tests, brain CT. All are clear no issues. Have BP and in medication. It will be usually 140/90 in general.
