I have what feels like a lump in my nasopharynx. Have been to my ENT and Primary, they both seem to think it s allergies. No endoscopy. (I also have muffling in both ears that they deduct is from excess fluid bilaterally and previous membrane rupture to the left 6 years ago ) I have tried every allergy med known to man. Today I woke with what i would describe as trails. Not 1970 s trails, but a literal wave that followed my line of vision, no matter where I looked, or how I turned my head. It only lasted approx 3 minutes, but enough to concern me. Thinking this could be related to fluid build up, causing imbalance/disturbance? Or should I get a scan?
