Hi, I am sorry to know about your mother s condition. She is probably having a stone in the ureter (the tube connecting kidney with bladder). Since it is a very painful condition and can affect kidney function and/or general condition, it is very important that she gets medical attention as soon as possible. There are excellent medicines which can control the pain within minutes. However, I cannot prescribe them online. Once you get a confirmation of diagnosis using ultrasonogram and urine microscopy testing, your treating physician will be able to sole the problem very quickly. A single dose of over the counter pain medication can be given for emergency (if she does not have pre-existing liver or kidney disease). Make her drink a lot of fluids. I am available for further guidance at any point of her treatment. Wish your mother a speedy recovery, Best regards, Dr. Raguram G MS, MRCS, MCh (Uro), F. Endouro Endourologist AUKI
