[|Human|] I have a 9 cm lymphnode and my doctor put me on an antibiotic to see if the swelling will go down. It s so far not working and now I have a very swollen and very painful bump on my birthmark near where my leg and butt meet but inner and it s purple and red like.
[|AI|]  Hi, Dear,Thanks for the query to My Chat Doctor Clinic. I studied your query in depth. I feel concerned about the worry you expressed. In my opinion-the painful-bump non-responding to antibiotics-is-mostly-a Lipoma at the Sacral Dimple with a subdued spina bifida underneath a purple-reddish-Birthmark.? Ant that's why antibiotics not working-for the pain.?or could be Colonial Sinus ? I would advise -MRI study of the bump and consultation with a pediatric surgeon / and ortho-surgeon / and or-neuro-surgeon- who as a team could be of help in planning right treatment. The pain does not appear to be due to infection / inflammation, but is due to the stretching of the neural fibers around the lipoma over a spina bifida, which is the possibility from the facts of the query. Hope this would help your query. Wehe ll come for more queries to Chat Doctor. Have a good day.
