Ever since being diagnosed with mono last year my spleen hasn't been the same. I can't drink like I used to because my spleen seems to become more enlarged with alcohol (sometimes I feel a bulge underneath my skin), and it is accompanied with intense pain that feels like I'm being stabbed. When I don't drink there is no pain, yet there is always pressure and I can feel my spleen whenever I press on it. It is very uncomfortable and it is constant. Nothing makes it feel better. I went to the hospital and they did an ultrasound. I was told that my spleen is of normal size and they were unable to detect anything. I could have sworn that my spleen was the source of all this, but now I'm being told otherwise. All the pain and discomfort I get is located exactly where it was a year ago when I had mono and it was in fact enlarged. If it's not my spleen, then what could it be?
