Hi Thanks for writing your query After going through the brief description of yours, you have developed an abscess, as you are already on antibiotics all you have to do is daily dressing .You may take trypsin to reduce swelling. If the pain and swelling subside well and good otherwise you may require a small surgical procedure called as Incision and drainage to clean the abscess cavity. Hope this information helps you. If the problem persists see a doctor. Take care and I shall be glad to answer any further query. Regards Dr.chugh Orthopaedic surgeon http://bit.ly/drmchugh
