Thank you for your response. The problem is that JAR-FCL3 reads that if you have a chronic shoulder dislocation you need surgery. This is what the AME told me "come back after your surgery".
So that is a problem, the second problem is: My shoulder is very unstable two nights ago I woke up because it was dislocated. It really is a serious problem.
Nevertheless I will go for a second opinion and see what they will tell me. I am really afraid to loose my medical permanently!
Again thank you for your tips and I will certainly try to follow them, however the conservative method might be not a solution. I will ask the AME as well if this is a possibility.
@homonculus, It sounds like you've got experience with the surgery and the recovery process? Will the armfunction be completely back after surgery and will it be possible to press buttons on the overhead panel etc.
