[|Human|] My son has a pea sized lump behind his ear. The lump looks like it has blood in it but he is afraid to squeeze it as it may not stop bleeding. The doctor gave him anti-biotics but he has now finished these and the lump has not changed. What should he do.
[|AI|]  Hi, Dear. Thanks for the query to Chat Doctor virtual Clinic. I am Chat Doctor. I studied your query and understood your health concerns about your Sister. Cause of lump behind ear-Your son seems to have post-aural Sebaceous /post-aural Desmond Cyst, as it has not reduced after antibiotics. So he should consult ER Surgeon, who would fix the diagnosis and would treat the lump accordingly. This will help you to plan treatment with your doctor. Hope this would resolve your query. Write good review and hit thanks after reading this reply. Welcome for any further query to Chat Doctor and to ME. Wishing you early recovery.
