      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Each participant's name and type of intervention (placebo or zinc sulfate) are written on a piece of paper and enclosed in an envelope. The envelopes containing the names of the participants will be placed in one box, and the envelopes containing the type of intervention will be placed in the other box. An uninformed person first picks up an envelope from the first box and then from the second box and gives it to the study coordinator. The coordinator writes down the participant's name and the selected intervention type. The process continues until all boxes are emptied, Blinding description: This study uses a placebo similar to zinc tablets that have similar appearance properties. Patients are not aware of the type of substances they receive and are unaware of their intervention type. Also, health care providers and evaluators of the results of interventions do not know the patient groups and the type of medication received.</study_design>

      <i_freetext>Intervention 1: Intervention group: Patients in this group, in addition to routine medications, treated with zinc supplements (made by Abian Company, containing 41.4 mg of zinc sulfate) will take daily intake for 1 month. Before the interventions, after 2 weeks and 1 month, the amount of pain and chronic pelvic pain will be measured and compared by a questionnaire. Intervention 2: Control group: Patients in this group will receive placebo tablets daily for one month in addition to routine medications. Before the interventions, after two weeks and one month, the patients' pain and their chronic pelvic pain will be measured and compared by a questionnaire.</i_freetext>
