Query: Think my Pu erh was bad

This is (was) my first time to try Pu erh so I have nothing to compare it to but from everything I read, it is supposed to aid in digestion which is just the opposite effect I got every time I drank it. Every time I have drank the tea, I get a pain in my diaphragm like I have to burp but can't. I thought it was something I ate so I tested the theory. I quit drinking the tea and felt okay, I have drank the tea every few days without changing anything else in my diet, and every time I have drank the tea the same thing occurs.Not sure if this has happened to anyone else while drinking this brand. I probably should buy some other Pu erh and try it but I'm a little hesitant now.
