I had a fever with mine. I also had nausea and vomiting.
Push in the right lower quadrant of you abdomen slowly and then release fast. Does it hurt really bad with the release? Stand on your tippy toes, fall on your heels hard; does that hurt really bad?
Honestly, don't mess around. Did you at least speak with your PCP and get input as the route to take? I do remember that I could barely straighten up and kinda walked crumped up bent because that was most comfortable.
Let us know how you are doing. Good luck, and hopefully you will have a wonderful Thanksgiving!
