[|Human|] My son (6 year old) has a large, hard knot on his mastoid bone. It is towards the top of the bone. He has no other symptoms (no fever, ear ache, etc.) and he says that it doesn t hurt. He just found it a few minutes ago. Should we take him to an after hours doctor, or is it something that we could wait to see how it is tomorrow?
[|AI|]  Hi Thanks for your query and welcome to Chat Doctor. I have gone through your query and understand your concern. It is not an emergency you can wait for routine examination by Doctor. It may be a benign lesion, so examination by surgeon will be useful. You can discuss with your doctor about it. Hope your query get answered. If you have any other don't hesitate to write to us. Wishing you a good health. Take care.
