Sorry, haven't read the whole thread (have 5 mins of MN time!)
Dd2 has a lump on her shoulder, which has been under investigation since she was a few months old ( she is now 14 months ), so far, the paed has suggested it could be a haemangioma, a cyst and a cystic hygroma (sp?). Because she has exczema, it has become infected twice, and so they were going to surgically remove it. The surgery was cancelled ( a cold ), and it was then decided to leave it for 6 months to see whether it changed, it hasn't, but where it was infected she now has a red square on her shoulder.
It was at smallest the size of a pea, and at largest a grape. I was in a state of panic, when I first felt it, and until they drew fluid off and said that it was not cancer related (I don't know why, but I felt like an idiot for even suggesting it), I was so worried for her.
We rang and asked to be seen immediately, when the lump suddenly looked different (it had been colourless, and suddenly looked a grey blue colour), this was when it was discovered it had become infected. So if you are worried about anything, please ring the hospital, because they may be able to see you sooner. We went in the same day, but had to wait for ages, which was fine for us.
Sorry for long rambly post. Hope it gets sorted out soon.
