DS (5.5) has a bruise in the middle of his chest, just slightly off to the left-hand side since last Friday or Saturday (we can't remember).
No-one (including DS) remembers it happening.
It has a lump in it.
My mum is worried and thinks we should see a Dr but I'm not sure. He isn't complaining about it hurting (he makes a right fuss when something does hurt) and has no other recent symptoms (for the past 5 weeks he's been complaining about a tummy ache, but we had a scan for that and its swollen lymph nodes on his intestines - the pain has almost gone away).
If I go to the Dr with just a bruise, I'm afraid she'll think I'm a hypochondriac as we've been three times recently with DS's stomach and the last time we had blood tests which came back almost normal.
