My daughter got her MMR on August 1st, now 15 days later she has a lump on the same side of the vaccine. The GP had us schedule a Pediatric Urologist and said it could be a hernia that needs surgery. I am very scared. Could it be a lymph node, hernia. I saw some posts about Eczema accompanying swollen lymph nodes and she does have a lot of eczema. Please comment if you have any advice. Thank you.
