Five years ago I was drinking heavily, really heavily, I cloud not quit without severe withdrawal, I had to go to the emergency room as my lower extremedies were filled with fluid, I was on a methadone treatment for opiad addiction as well. I went through all sorts of test including a cat scan and the outcome was that I had lower extremity edema , and a lesion on my pancreas. Unfortunately but I have a greater sense. What does lesion mean, no one ever explained
