It would not be possibe to comment on this without a clinical examination of the lupm that you are describing.
Since when was the lump noticed?
Because your child is only 7 years old , it would be best to see a pediatrician for a proper clinical examination and see what he/she has to say about the lump.
Do not try to manipulate it or try any home remedies without consultation with a pediatrician.
Do let us know what the doctor tells you.
My pediatrician is sending us to a surgeon tomorrow for evaluation.
How hard is the lump actually - is it bone like or mass like?
Also,a sk your doctor for a chest xray.
Do let us know what the surgeon tells you.
Any update? I took my 8 yr old daughter in to urgent care today for something similar. All he could tell me was that it was on her collar bone and not a lymph node.
