based on your complaints it looks like it could be a case of kidney stones. please go to your nearest hospital and get an x-ray kub (kidney and urinary bladder) done. sometimes kidney stones are not visible on an x-ray. in that case further tests might be needed. usually small kidney stones are eliminated by the body on their own while passing urine. in case it is big in size treatment is necessary. however as a first step please get an x-ray done. for further information consult a general practitioner online --> <link>
