I was diving today, and I have had a cold recently and while diving I was having pain in my sinus region.
It did hurt but I was more concerned with "the hunt." Actually got some good fish today.
After I get on shore I take off my mask, and blow out as usual expecting the whole mess of stuff that accumulates in my nostrils to come out, but I got something extra, a shit load of blood in the mix, almost like I had a nosebleed, (really red blood). I have never had a nose bleed before though. Did I mess my self up. Just asking maybe someone else has experienced this.
