Hi Laxman. Im a scuba diver and was having
sinusitis for quite some time. Now finally I have got good control. Don't worry u will be able to go diving without
suffering from all the pain. its not so much the
cold temperature but the
pressure changes that causes sinusitis to occur or flare up after diving. I was on a relatively long course of
antibiotics to clear out my infection. Since then I have been taking precautions everytime i go diving.Particularly important to avoid diving when you already have sinusitis because that is sure to worsen it. Im sure a good doc will be able top help you. All the best.
