I have allergies to cats that result in sinus congenstion. (of course we have two cats...) so daily meds keep my sinuses clear (zyrtec and singulair) - I was cleared to dive and have had no problems so far (only 20 dives under my belt, but so far so good)
As others have said, as long as you can equalize on the way down and back up, you should be ok. Just take is slow and don't push yourself and of course, consult a good DR or ENT.
