Okay it all started about 2 years ago. I traveled to the uk and while I was there i caught a cold. Simple right, not quite when i got until to the plane i had to constantly clear my air passages and my ears felt blocked during the whole entire flight. Now I am still having that problem the cold is gone but my ear still feel blocked and now produces a crackling sound. I went and saw an ear specialist and he couldn't give me a definite answer and that cost me at least 400 hundreds that i cant afford again. Please I need help with ears okay its been bugging me and i am scared it's something much worse like i could lose my hearing.
