It is constant for the most part. I can tell you the day it hit was Dec 12
2010. I have had my gall bladder checked, upper-lower GI., hidascan, mri, catscan, ultra-sound and xrays taken. My appendix was removed about 7 years ago. The pain in my side sometimes begins a trickle effect that tickles my skin or causes me to be sensitive to having my clothing or bed covers touch the surface of my skin.
