three R's (redirected from r)
the three RsThe three tenets of education traditionally considered the most basic or essential: reading, writing, and arithmetic. (So named for the prominent "R" sound at the beginning of each word.) When a school begins seeing major performance issues across the three Rs, then it is time to revise its curriculum and teaching style.See also: RS, threethree R'sThe fundamentals of education, as in It's a terrible school; the children are not even taught the three R's. It is widely believed that Sir William Curtis, an alderman who became Lord Mayor of London, once presented a toast to the three R's-reading, riting, and rithmetic-thereby betraying his illiteracy. In any event, the term was picked up by others and so used from the early 1800s on. See also: threethe three ˈR’s (old-fashioned) reading, writing and arithmetic as the basic school subjectsWhen you say these three subjects, they all have the sound /r/ at or near the beginning of the word.See also: threeR

Well it all depends on how long these pains have been going on. If it is a matter of 1-2 days, this pain , if very very strong and accompanied by nausea or vomiting, can certainly be an acute appendicitis attack, which should make you hurry up to seek medical attention. If the pain is tolerable, and has been going on for more than few days, it is not compatible with appendicitis pain, but can be a lot of other reasons, for instance- gall bladder problems (for instance - stones) or renal stones.
Either way you have to see a doctor about this pain if you want proper diagnosis and treatment.
