Oh, it's gross.
DS (4yo) had said he had a painful bottom so looked at it after bath. Red ring round the anus. Then I looked again and there was a blue/black lump (at 3 o'clock IYSWIM). I called DH to look two mins later - no lump. The we both looked again 5 mins later and yup, blue black lump back (this time at 12 o'clock).
What is it? Anyone know? I'm completely freaked out but trying to be casual with DS. I would appreciate any suggestions. GP shut til Monday and I guess it's not an emergency...
If it's relevant, he has recently developed a rash on his bottom (but higher up) which I just assumed was mild ecsema.
