DD currently has chicken pox and it is quite bad on her scalp. However I have noticed a hard lump under the skin on the bottom right hand side of her head about 1.5 inches behind her ear and just above the muscle that runs up from the neck. Its about 1cm round and doesn't move about. I of course started to get worried sick. Then I thought perhaps its a swollen lymph node from fighting the virus. Can anyone tell me if there is a lymph node around this location or what this lump could be? I've felt my own head and cannot feel anything like this in that area. It is not a result of a fall or anything like that.
Many thanks for any ideas
