Sed rates alone aren’t very helpful, but your deep, burning pain isn’t normal, and they may well be related. Does the pain always go along with the gurgling? Do you have more gas than before all this started?
One possibility that comes to mind is that you may be having brief obstructions around an adhesion, which stretch the intestine painfully. Even after they clear things could hurt for a while. This explanation fails to account for your fevers and elevated sed rate, though.
I guess you might have an intermittent leak or fistula that failed to show up on your CT and MR enterographies. That fits the fevers and sed rate elevation better, but can be very tough to pin down.
I hope you can find a doc willing to help you figure this out!
