Hi, I am trying to figure out what is wrong with me. I had a slip and fall accident on 06/27/2012. I suffered contusions on my right shoulder, sprained thumb, hand, wrist and lumbar spine. I have been using tramadol and mobic. For the last three days I have been feeling pain, pressure in and around my belly button. There is also a clear smelly liquid leaking from it. I have also noticed blood and blood clots in my stool for the last two days. What could this be?
