Hi, my friend and I were messing around and he ended up punching me in the lower right rib. I felt a slight pressure in that area for a few days, but then it subsided. However I noticed where he punched me there was an indent left there, and I can still feel the slight pressure. I don t feel pain when I breathe, so I don t think it s broken. What could it be? Also, the indent seems to be getting smaller, but I am worried.
