Four month jabs were two weeks ago and I've just noticed DD still has a lump in her leg on one side. I say "still" - I didn't really notice at the time, but I'm presuming it's from that. Is this likely/usual/okay? There's lots of information about side effects that mention lumps lasting for a couple of days, but obviously this is a lot longer than that - and I'm only fairly sure that this is where it's come from. Has anyone else had a jab lump last this long?
