Hi. For the past few days ive been having weird pains all down the left side of my body. Including my chest. I went to the e.r. and was told it was plurisy, which was weird to me because I didnt know pluricy ran all through the body. Im syill having these bains, plus now I have diarrhea that is yellowish and watery that burns really bad like acid and im going like every 10 minutes, but I dont have pains like I jave to ave a bowel movement. It just comes? What could this be and should I seek immediate attention? Thanks in advance.
