I am experiencing pain under my ribcage near the bottom where it meets my stomach. I ve felt this before, off and on, for a few months, but it usually goes away after a half hour or so. Tonight it has been going on for about four hours already. It is mostly a feeling as if I got stomped on, but I also get sharp pains every few minutes. I m a 29 year old female, I don t smoke, and I rarely drink. Please help!
