f4'>forgot to mention the saline test. I've also had th8
f4'>is test and my understanding 8
f4'>is it helps loosen any nasty stuff in your lungs so it can be coughed up and analyzed. My chest also felt "tight" afterwards, but th8
f4'>is feeling did not last long (maybe a day). I use 8
f4'>albuterol, which also causes "shakiness", so I imagine th8
f4'>is a typical reaction to most bronchodilators. Sorry I can't be more help.
