If there is an increase in white blood cell count AND blood in the urine, then you probably have an urinary infection. You can request an abdominal ultrasound to check for kidney stones. Microbiological analyses can identify any possible infective agent and its sensitivity to antibiotics. Proper protocol is a prescription antibiotic to treat the urinary infection. Additionally, peptic ulcers can cause the pains you’ve described, but urine analyses are a good beginning for diagnosing your condition. A gastroscopy can confirm or exclude the presence of a peptic ulcer.
