What Causes Dull Pain On Left Side Of Thorax Post Alcohol Consumption?

Question: Good afternoon, Doctor,

I'm 23 years old. I used to drink regularly alcohol between 18 yo and 22. I've totally stopped in XXXXXXX 2014 and very recently, as I'm staying in Germany, I've drunk several times around three pints of beer and some whisky.

Thing is that I feel like a sort of dull pain afterwards on the left side of my thorax. Maybe around the spleen, that's my suspicion. A pain which fades away before the end of the following day. My liver and spleen were a very little bit oversized on the echographies I had last year but nothing serious at all. The size was even reduced in the last one.
So my question is: what should I think of these symptoms? I also suffer functional dyspesia of the stomach and confess I don't do much sport, even if I have a normal corpulence.

I sometimes imagine the worst. I've stopped drinking for more than six months and it seems sad to me to give up alcohol totally and for good as I'm so young. So what would you recommend?
Thank you for your answer, Doctor.

Have a good day.
Best regards.

Hi again Dr. R.K and thank you for answering that fast.

You have properly understood my post.
Thing is I already had an upper GI endoscopy last year before making a pause with alcohol and they only diagnosed "functional dyspepsia". Can it cause such pain?

At the time I had this endoscopy, I had these same symptoms along with reflux and stomach burning. I still had them after consistant meals even after having stopped alcohol a few months.

So for you, it comes probably from the stomach and not from the liver or spleen. How come my dull pain is on my left side? Should I have another endoscopy even if the symptoms are the same as before? Could they have missed my real disease? As for the treatment, what is Prilosec?

Sorry for so many questions but I'm a bit worried about all this.

Best regards
