What can it mean if I am weak every day, I have pain when peeing and terrible abdominal pain?

Pain when urinating may indicate a urinary tract infection. If this is accompanied by "terrible abdominal pain" and there is a sensation of "weakening", then please do not delay, but contact your doctor. At the same time, please note that it is not possible to make a diagnosis via the Internet - if you want to find out what exactly is wrong and how you can take treatment, it is advisable to undergo a test - even a general one (temperature, pressure, heart rate), palpation of the abdomen, presumably the doctor would also order a urine test.
