I got burning sensation in urine 2 weeks ago. My GP doctor advised me to do urine routine test. It was detected with bacteria present, 18-20 pus cells, urine protein absent. I was advised to take oflomac 400 once a day, urispas 3 times a day, and alkorina syrup 3 times a day for 5 days. After taking I got some relief, but 2 days ago, I again got burning sensation in urine. My GP again advised me urine routine test. My pus cells are now 1-2, no bacteria present, but protein traces found. I have been advised to take alkorina syrup for 10 days thrice daily. What could be the cause of burning sensation again if there is no bacteria? Will taking alkorina again for 10 days cure it?
