Jim - I am about 9 months out from the same surgery that you had, but did not have to have RT. I have the same problem - it happens when I yawn, but not every time.... I asked my Dr and he said it was related to the nerve damage from the ND and that it might get better or even go away.. or it might not... So I have just learned to live with it - but it really hurts when it happens, doesn't it??!!! Sorry I don't have a cure...
