Hello, Welcome to the forum. Since you have PID, you can be infected with (E. Coli) Escherichia coli infection. When infection gets chronic and spreads in the urinary tract, patients generally complain of such symptoms.  Just take care of your hygiene and sanitation. Avoid swimming and using public toilets. Avoid having sex till you are not fine. Wear cotton undies and treat them with salon, wash them regularly. You should have an R/E urine test and also a C/S of urine to confirm your infection.  Keep yourself HY Chat Doctor.  Take soups, juice also. Antibiotics like Norfloxacin and taking Alkacitran with water can help you get better.  See a doctor and get examined before taking any medicines. Take care.
