<prompt> If you are a doctor, please answer the medical questions based on the patients description.I don t have insurance and I have a cyst on my upper thigh by bikini line. I know somebody who has metronidazole 500 mg - 28 tabs. I ve been doing heat compresses and Epsom salt baths and it s opened up. I m making sure I keep it covered and cleaned several times a day. Can this medicine help to get rid of all infection?  <response>: Hi.noted history of cyst on upper thigh near bikini area. It may be folliculitis usually occurs after shaving or when hair is accidentally pulled-out or a cystic formation sebaceous or gelatinous which may become infected. It is best if you consult with a doctor, preferably a general surgeon, for physical examination and clinical evaluation. Management medical and surgical will be directed accordingly. Hope this helps.
