Hi,
About a month or two ago, I believe I had strained some muscles while working out. The pain didn't happen right away maybe one or two weeks afterwards. At first it stemmed from my neck, shoulders, and upper back. Soon after I started to feel pain in my chest, both sides right by my armpits, lower back, and abdomen area especially on my right side. The pain is usually sharp. When I do sit for a long period of time, both my right and left sides hurt but more on my right. Recently I had diarrhea for three days straight and then feeling constipated. I would sit in the bathroom for an hour or two straining to push the stool out but nothing comes out. Before that, my bowel movement was fine. I tried drinking prune juice and using one of those laxatives that you insert into the rectum to make it easier to go. At first, it did help in relieving my bowel movement but I would have diarrhea followed an incomplete evacuation of my stool. Now when I have the urge to go, sometimes only one or two small stool comes out and then straining again but nothing comes out. I was wondering if I might have appendicitis or IBS. I read that one of the symptoms of appendicitis is having a slight fever but I don't have a fever. Do you have to have a fever to have appendicitis? Also, is having lower back pain causing me to have constipation? Please help.
