sorry but where did the sinus problem and the heart murmer come from???
In medicine we have to deal with the entire pathology. You can't just add another diagnosis and assume it isn't relevant.
If you have had sinus issue they will need investigating or confirmation they have resolved. Until then the symptoms you put down to unnecessary drugs might be sinus symptoms which might cause dizziness when flying
There has been a recent thread on murmers but that may well need investigating too
It can be difficult posting if you don't know the relevance of various problems but if something is missed out the advice you receive may be incorrect
Best to discuss with your AME who should be able to advise on getting an unrestricted medical in the future
Good luck
