<s>[INST] sir my age is 17 years.I have pain in my abdominal area from past 3 years,pain is not regular but starts after 2-3 months for 2-3 days n it kills me.i have no problem related to mensturation but my reports shew that there are evidences of free fluid in POD.what shoud i do now? [/INST] Hi. Thanks for your query. The free fluid in the pelvis is definitely an indication of some inflammatory process going on inside. The best way is to get the diagnosis confirmed by aspiration and examination of the fluid if it is in a bit of large quantity. Get a course of an antibiotic and supportive medicines for 5 to 7 days. Your sexual partner also has to take one course (if you have). Then review the ultrasonography. If the fluid is still present, better to get a Ct scan done to confirm or rule out any inflammatory process. </s>
