First of all, thanks for great answers!
Well, I went to an ear specialist, he also told me that a single shotgun shot could be dangerous but unlikely, he told me he had shot 100 of shots without any problem, but also every "ear" is different.
He could not find anything wrong, I aslo did a hearing test with exellent hearing on both sides. He told me to ignore the tinnitus, but that' is easier said than done...
Regarding the airsickness, he thinks it's maybe psycological, since I worrie to much about the situation. He said thinking of airsickness can actually make you airsick...
Well, I got this week off, so I can relax a bit before doing all lot of up and downs again, I work with calibration of ILS systems, so that mean a lot of manuvering, and not a whole lot of straight and level.
Anyways! Thanks !
And you think the tinnitus will eventually go away, or is it forever? Strange stuff...
