I had my ears syringed after suffering very bad T after a rock concert. It was bad in one ear and not the other. This syringing cleared up the bad ear completely but left a very very mild rining in the other. This disappeared into the back of my mind within an hour and and I didn't hear it for about a month. Then I got a head cold (mid Jan) and it came back, in both ears. Not bad, easily losable in background noise but noticeable when it's quiet. I assumed it might go away, but two months down the line and it's still there. It doesn't bother me day to day but I notice it when it's quiet. I was thinking about it last night and I could hear it over the TV (because it was on my mind!). Should I go back to the GP (it's been 2.5 months) to see if I have more/different wax build up? My ears were completely blocked by it previously!
