My symotoms are significantly better now at 9+ months. I had sleep issues fir 8 months, and tinitus for only 3 random occasions along the way; 2-3 days each time. Low frequency buzzing, heavier in one ear than the other.
I have also had swollen lymph nodes all 9 months, one of my last remaining symptoms. not sure it is related to tinitus.
Last week I randomly had tinitus again, 3 days, and it came back with mild to moderate sleep problems (poor sleep, cant stay asleep, vivid/scary dreams, night sweats). Tinitus went away after 3 days again this time.
Still dealing with the sleep problems but they appear to be getting better too. Not as bad as they were the first 7 months.
