Hi
My baby boy has a lump that is close to 4 cm in diameter- in his groin area. He is otherwise eating and being his usual self. I have taken him to the GP who has asked us to return in 2 weeks for a check. I am concerned after reading up on the internet and also following a similar thread on mumsnet. He did have his MMR vaccine three weeks ago and I noticed the lump soon after. It has been 10 days and no change in the lump.. any similar experiences ?
