Hi Everyone, thankyou so much for your kind replys and advice.
Tightslot i appreciate your comments but as i said in my origional post i have already discussed this with my GP who has assured me that I do not need to give up flying and am not doing any damage to my ears unless i continue to fly with a cold. As long as i dont do that she says i will be fine. She also sympathised with me as she said that it wasnt uncommon and as a keen scuba diver herself she suffered the same problem.
I had a medical when i joined the company who said my ears were fine.
FBW your right im not yet at stage one but am now on edge that i dont go sick again before the 12 months are up. I hope you are well now FBW and good luck to you to
