I jumped into the pool and started swimming to the bottom of the 12 ft level. I started feeling a sharp stinging pain behind the eye and where the sinus cavity is. When I surfaced the pain would disappear.

Doctor, doctor, it hurts when I do THIS! . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Well, don&#39;t do THAT? Seriously though, if I have any weird pain or soreness while working out, I try to work around it and leave it alone for a while. Such as if my left arm doesn&#39;t like the motions of one of the Nautilus machines, I skip that station for a while. -eric<div style="clear:both;"></div>https://community.usms.org/thread/92484?ContentTypeID=1Sun, 08 Nov 2009 06:09:02 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:2fbbd621-fdbd-42fc-be6e-ed1b449ea717Former MemberHad the same issue yesterday...guess i&#39;ll see a doctor if the same thing happens today<div style="clear:both;"></div>https://community.usms.org/thread/92397?ContentTypeID=1Tue, 15 Apr 2008 15:55:13 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:0a655bd3-aa58-41e1-b80a-ff21013563b1Former MemberHave your doctor check you for a sinus infection. This is exactly how I discover whenever I have one. -LBJ<div style="clear:both;"></div>https://community.usms.org/thread/92317?ContentTypeID=1Mon, 14 Apr 2008 10:50:19 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:ef638d99-4efb-49e7-bf9e-71c5cd66b062Former MemberIt was painful enough that I had to surface immediately. The pain radiated from my eye socket/sinus to my nose. I was concerned that it might be a warning sign of another problem. I noticed when I swam on the surface, after it happened, I was fine and felt strong and healthy. Is this a pretty common thing that isn&#39;t necessarily anything serious?
