I have a soft like balloon lump on my left side of neck and shoulder about 3'' round doe'nt hurt 6 mo. old comes and goes ??
Hello, this is Dr. David. I have read your question and I'm ready to help.

it could be a seroma (benign fluid collection) or a lipoma (benign fat mass)

an ultrasound of the lump can tell if it is fluid inside or solid inside.

do you have a doctor you can see who can order an ultrasound of the lump to see what is inside?
