I was surfacing the other day from an 18m dive after being on the bottom for over a minute and about six meters from the surface I felt like a hot flush running through my body and got a ringing in my ears. I thought that was it and made a dash for the surface. When I got there I felt fine.
A few dives later I had only been down to 7 meters for about 20 seconds and got the same felling on the way up. What the hell was that?
After 20 second apnea I don't think I can get a SWB can I?
I had been doing 1.5 - 2 minute apneas with ~2 min rest for quite a while between 10 and 20 meters.
Could the water being colder than usual have an effect?
I hope someone can help.
