[|Human|] Pea sized lump behind ear skin colored. Sore to the touch feels like a pimple. Had it for a week and it hasn t come to a head. Tonight in the shower I was finally able to pop it but the blood was dark red. Been ten minutes and it still kind of oily red.
[|AI|]  Hi! Good evening. I am Chat Doctor answering your query. Most likely this could be a post auricular lymphadenitis with pain due to some inflammation. If I were your doctor, I would advise you not to fiddle with it to avoid a super added infection. I would prescribe you with a course of broad spectrum antibiotic and an anti-inflammatory Chat Doctor.  Otherwise, I would refer you to a general surgeon for the possibility of an FNAC/excision biopsy to arrive at a definitive diagnosis for further management. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
