Well iv had really bad dizziness for over 2 years now,iv had every test you can think of,i had a vestibular assessment yesterday and he said my hearing is great and my ears are perfect.iv had blood tests,urine tests,adrenal test,eyes/ears tested,24 hr ecg,blood pressure,blood sugar all checked,the only thing i had to go on is on my MRI scan i had a few months ago they said it was fine but i had a blocked sinuses.i Saw a ENT Specialist that requested a CT scan on my sinuses and a vestibular assessment.I got a letter today saying on my results of my ct scan there is a small mucocele in the right ethmoid sinus but no other abnormality detected.Could this be the cause of my dizziness everyday,vertigo and vision problems? yet my vision is "20 20" as the eye test guy said and my balance in my ears are fine.I all so had bad fatigue,weakness,generally feeling unwell,pain in ears,bad nausea.Could this be the cause? please say yes! haha :P thanks in advance
