Well, I'm glad you've found a Dr you are happy with, it makes a huge difference! Glad to here she isn't too concerned. It sounds similar to my DD the other week. We had a lump in her neck checked at the GP, were then sent for an U/S then a chest x-ray and it all came back fine. She just has a freaky vein that pops out when she cries lol! I reckon it'll be a cool party trick one day .

Hope the u/s comes back fine and I hope you're feeling a bit more at ease
