thanks for your replies everybody. lol i know what equalizing is like and it was not that, it was equalizing in the sense where i would apply more and more pressure until i suddenly felt it pass into another part. that part was not my ear, it was my cheek where my jaw meets my skulls. and i do infact here crackling, and i did this on the surface, exactly like naids case. lol i didnt pull my cheecks, just inflated to see if i could make my face bigger
as for the packing thing i just did it to see how much air i could get, and i was on my bed, and i felt a pain in my intercostal joints, so i stopped. using my abs to lift myself made it hurt, so i let my air out. i generaly dont pack that much anyway. so what is the pressure in your lungs whilst packing (like i did) and when assending with compressed air. my point is if people dont notice the air expanding in there lungs, and dont feel pain, then havent i already exceeded that pressure?
and crusty, are you saying if i pack hard enough on the surface (for example untill i feel the pain) and i dive and comeback up, air can get trapped and cause barotrauma?
