Hi Doc I am a 38 yr old male 60kg i had a average pain in the btm of right hand side ribs yesterday, the whole of this area tightened up somewhat and as i felt it i felt only what i can describe as a hot pad on my right hand side ribs which contains fluid, which i could push and prod with no pain. I checked my left hand side of ribs and there is a similar fluid pad like thing but on the upper side of my ribs and not as big as the left hand side. I can push these fluidy pad like things around a little. My wife was pretty scared when she felt the big pad on my right side. Any info idea s would be greatly appreciated. Many thanks
