This is the third time I have sensed a lump at my right abdominal. First time I noticed was during my trip to Hokkaido in July this year, when it was after a wine tasting session. Second time, was just two months back, end of August after drinking at YZ's place. After that, been to the doctor, had my ultrasound and blood test. Test results are normal. Thirdly, yesterday, after having some wine at wedding dinner and some lime alcohol with HL.
I wonder what is it that caused the lump?
