I had ear fullness at one point. It went away after 2 weeks, but it can take longer for others. It seems you've had it for around a month? Some people on TT had their ear fullness go away after 6-7 months. Try to hang in there, it may resolve on its own eventually.
I'm there with you. I understand. Maybe one day it gets better. Or we get better. Man this is so sad.i really feel for anyone suffering from this condition. Maybe one day it gets better for us. It has for so many.
