Gastritis causing me a lot of issues

[alik93]

Over the past 5 years I haven't been feeling to good. I'd always have stomach pains, sweats and red skin after I did a shower. I'd also get bladder pains and a discharge after masturbating. In 2015 I went into hospital because I lost my voice and my stomach pains wouldn't go away. I had a endoscopy which showed I had Gastritis, H Pylori and Tonsil cancer. They gave me special meds to get rid of it, which it did. Last year (2016) around Easter time I had the urge to masturbate but after I did I felt a pain in my bladder again. Next morning I woke up and my mouth was full of acid. I checked in the mirror and my tonsils were swollen. I didn't feel well for 3 days either. I went to the doctor and he said it wasn't anything to bad. He gave me omeprazole, which didn't help. I'd continue going back every month but the doctor still wouldn't do much. In November I changed my clinic and the doctor there was a lot helpful. He referred me to a specialist and the specialist is going to send me an appointment for another endoscopy. I'm still having problems with my bladder after masturbation. The doctor thinks my bladder has some inflammation that's why I'm getting the pains.

Does anyone else might know why I Keep getting his bladder pain? maybe it's something to do with the gastritis? Also why has my Gastritis came back?
