Already been thru the ENT. Look clean as a whistle and, as I told him, my hearing is superb (looking for growths in ear drum area). Biggest obvious problem was deviated septum on right. But not something he would pursue as likely cause of pressures & imbalance.
Hmm. What about possible allergies ? Also, are there times of the year when the symptoms are lessened or more pronounced (with respect to head pressure) ?
