I am new to the forum. I went diving at Lake Tahoe CA on Monday the 20th of August. I have had problems with my balance and dizziness ever since. Being new to the sport, I didn't know about the dangers of hyperventilating, etc. I was hyperventilating a little before each dive. I was diving to about 40 ft. Resting for about 5 min. on my jetski and then diving again. About 6 dives total. After the 6th dive I notice my balance was off and dizzy to the point where I had to stop my jetski for about 5 minutes for fear of falling off. I rested for awhile and then did a series of shallower dives. For 5 days now I have had problems with my balance and feelings of dizziness. I was hoping it would subside if I waited it out but it hasnt gotten any better. Usually when I run off to the doctor I end up regretting it because the injury ends up healing itself. Any advice would be much appreciated.
