<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello. I have a question regarding pimples on legs. I have had about 15-20 pimples ranging in size on specifically my left leg, though it is on both. Some have white tips, some itch, some are very tender. I have them on the back of my left knee as well, hurting when I bend. They are very red, and dont go away easily. Could you please help me diagnose this? Thank you.  <response>: Hello, Thanks for the query, you might be suffering from recurrent folliculitis. It is a superficial bacterial infection. Take a course of antibiotics. Apply an antibacterial cream like mupirocin. Hot fomentation is also good, If you dont get any relief get a culture and sensitivity test done. This will tell you exactly what is the causative agent. Let me know if you have any other doubt. You can ask a direct question to me on this forum, following the below link. .comdoctors Chat Doctor. Thank you
