Hi Kim Seng & Ketam
Appreciate your time in responding to my problem.
Ketam - I have googled and learn a bit about sinus. The region sinus pain is not where I am having it. As such, I don't think I have sinus as the pain is on top of my head. I have never had this pain on top of my head before until I took the deep dive. I have never had a history of sinus problem. I wake up, I don't sound funny. Well, I have learned something about sinus.
Kim Seng - so far I have only logged 14 dives. My first 9 dives which is all within the 18m level, I have never experience this pain before. My air consumption during my 4 OW course dives at 14m average 44mins. I start at 200 bars and end at 60 bars. My latest at 7m is 65mins. Start at 200 bars and end at 50 bars. Is this OK/normal?
The problem started when I went down 30m in my deep dive. I start at 200 bars and end at 40 bars, av 45 mins. During my wreck dive, start at 200 bars and end at 50 bars, depth av 24m and av time 45 mins. Is this normal for most people who dive this depth?
BTW, I use medium size BCD and I don't smoke and drink.
My reason for asking about this issue is b'cuz I am now considering whether it's worth the pain-in-head everytime I surface after exceeding 18m or just be content with not going below 18m.
