I have been experiencing pain under the right side of my ribcage, for the 2nd day, now. I thought it was gas trapped somewhere in my bowels. No nausea, no fever, no dizziness. It ranges from sharp pain to dull. It seems accentuated when I walk or pick up my kids. I took 2 Advil PM and slept well last night, but today the pain returned. I first felt pain when I was at work on Monday and I thought my pants were tight,(haha!) and gas was trapped. I ate lunch as usual and went back to work. The pain did not go away. It feels as if it is localized in the liver area. Please help! Before I see a doctor, I want to find out more about localized pain in this area. Thank you.
