My buddy was recently treated for a bout of bacterial sinusitis. We decided to go diving about 2 days after all of his symptoms/sinus pain had resolved. He was fine for the first dive, but on the second dive, he got to about 2 feet from the surface and started having a great deal of pain in his sinuses so we aborted the dive. I'm just wondering if their is a recommended amount of time that one should wait before going diving following a sinus infection.
