Suggest Treatment For Swelling Under The Rib Cage

Last week while visiting San Francisco, I was desperate for a drink and so gulped down about a cup and half of Kombucha tea straight from the fridge. I didn t realise it was a health drink. I started having swelling under my left rib cage later that day. ALSO, that night I climbed over a wrought iron bed and leant on my left ribs with quite a bit of pressure, it was painful and I felt an egg shaped lump, (I also ate two energy bars and lemon cake from Chinese shop in San Francisco that same day) and am a bit confused as to which one I had the reaction too. At first I found it difficult to lie down and turn over in bed, the whole area feels very sensitive and I am wondering if I have a broken rib and swollen spleen. I am not sure what to do. I do not want to lose my spleen. I am an artist and have had spleen problems before but never swelling and pain. I think most of the swelling has gone down now.
