It only hurts if i pushdown on it.it goes away comes back,been to two MDs they both said not to worry,its a muscle.  <response>: Welcome to Chat Doctor .1. It could be a muscle as your doctor said.2. Possibilities of lymph nodal enlargement can not be ruled out.3. I would recommend getting an ultrasound neck none to evaluate the nature of the lump, its source, nature and extensions.4. Lymph nodal enlargement is seen after any infection inflammation local or systemic.5.Vascular cause also one of the possibilities - gets scan for confirmation. Good luck Hope it helps you.
