I'm scheduled to be on a liveaboard starting on May 27th, the last few mornings I have woken up with sinus pain, not bad, and I can clear my ears OK, but still fee a bit of pressure when bending over and such, been taking some Sudafed/sinus medicine. The pollen is really bad where I"m out now maybe this is the cause. Does anyone have any advice for a cure or will it cure itself? Is there anything a doctor can do? I just hate the thought of getting in the water and getting down the first 10 meters and feeling pain after waiting for this trip for almost 5 months. Any ideas would be appreciated.
