I have pain in my upper abdomen, just below my ribs. I've never had a bulled or strained muscle, but have played golf 4 times over the last 10 days. It was not painful while I was playing but seems to have gotten worse over time. The discomfort is steady and sometimes hurts more when I move. I don't think it is eating or drinking related as my digestion and bowl movements are not affected. I'm just concerned that its liver or gallbladder.
