Gidday,
In a previous life I had a session in a RAAF chamber, effects as described above, was a requirement in those "good old days"
In real lfe I had an outflow valve problem in a small Exec Jet, at 43000, cabin going up at 2500'/min, I got to 9500' rate of descent and met the cabin at about 22000 feet.
The pain was 20 on a scale of 10, head rang for days, was able to get it all sorted in a low traffic foreign Country, NEVER AGAIN I hope
Have seen the effects of colds, diving etc in the Pax cabin and in some crew, be careful, follow the rules and then give a buffer for self preservation. the You only get one set of ears and the bends are not pretty to watch, puts you off doing some things.
Be safe
