Recently I feel back pain. When I go to doctor he checked my b.p which was 150/90. Then he advised some test all test are normal but some infections are found in urine. Then he suggested to culture test of urine, sonography and prescribed some medicines. So the culture test of urine and sonography report will be arrive soon. Now my question is that what is the reason of my back pain and the reason of high b.p. The pain is left side of my spinal cord. He prescribed eslo 2.5 for b.p. Please tell something and help me.
