I am a PA and my wife made me read this wonderful post. I couldn't help but reply using her username.
First I am suprised by the number of people who would only see a PA for a cold........why do you need to see anyone for a cold?
The MD (or is it DO) with the BS and MS in chemistry is quite impressed with herself. I work for a lot of physicians who have advanced degrees....many of whom are total morons. And out of curiosity, why didn't you treat the pericarditis yourself if you are the greatest MD (or probably DO) in the world....it really isn't that hard.
Other than that NP's and PA's have about the same length of training, just different training. PA's in the medical model, and NP's in the nursing model.
Yes we bill the insurance companies the same as a Dr. visit, but they don't reimburse the same.
For the most part, people have been pretty pro-PA on this thread, some have been ignorantly or incorrectly anti-PA, I won't try and change their mind. I would recommend you visit your local Doctors office and visit the MD trained in Bolivia or Bosnia who completed their residency at a residency program who had to take the bottom of the barrel to fill their resident slots. They should treat you just fine for your cold.
By the way, swollen lymph nodes can be caused by a pimple, and probably wouldn't have been improved with antibiotics (as I'm sure you wanted!) and the stupid PA that treated you probably thought you were as dumb as you thought he was. In fact he is probably in the breakroom laughing about you with some smart doctors.
