Has anyone else suffered this? I woke up recently with my hearing, which is affected anyway, feeling as if I was 'underwater'. Can hear but my hearing is much worse and everything is muffled and distorted. Diagnosed with the above. Apparently a small thrombosis in a vessel in the inner ear, another APL side effect, but not common. Treatment is steriods, full ENT investigation to rule out anything else, then its presumed to be a clot and APL/APS cons then looks at upping anticoagulant. Wouldn't mind, but I can't do my job atm as I can't hear on the phones. 60% recover spontaneously but can be permanent. Hoping I am one of the 60%.
