Hello Doctor. Several years ago, I ate contaminated food, with e-coli, which gave me problems in the intestine. I binge drink once every month, sometimes I will go party once every 15 days, when I get bored. For a few years, I have been experiencing GERD, abdomen swelling, diarreah, and painful cramps in my lower abdomen, symptoms which become more present after drinking. I get pain about an inch down from my belly button, and to the right. I also feel pain when I notice transit on my intestine, specifically in that area. This is incredible pain, ussually minutes before I will go to the bathroom, and have diarreah. After going to the bathroom, I feel relief and everything calms down, I even feel my colon calmer. As of late though, I have been experiencing abdomen discomfort even if I don´t drink for a month or so, and I am getting a little bit worried. What type of exams or routines would you recommend? Is this serious? Thank you in advance for your response.
