Hi Chrissy,
Your not alone! I've been on daily meds for crohns since being diagnosed almost a year ago and i still have pain. Sometimes the pain is in my right rib cage and moves to my back, yet it's not my gallbladder. Other days the pain is on the left side. Prior to my diagnoses, I too had strange unxplained fevers that would hover around 100 with terrible stomach pain. Sometimes the fever would last for a few days, sometimes a week, it was very random. Even now I have random pain, no fever just pain all over and a lot of lower back pain. My GI says it could be the nerve endings reacting to the inflammation. Good luck!
