Use your fingers to gently press inward on your right side as far as you can without pain. Stop if there is pain.
After you have pressed inward and stopped, raise your hand up quickly and very fast.
If there is a sharp pain after you relese the pressure, there is a chance of appendicitis.
Since you have a temperature with the intestinal problem and blood in stools, I suggest you see a medical professional for a diagnosis now!
If it was me, I would take some food grade aloe gel, powdered ginger and barberry extract ASAP. I would also disolve a big pinch of slippery elm on my tongue and swallow it about 6 times a day or more, to coat and protect intestines and stomach.
