Please can anyone tell me they've had this and it's turned out to be nothing serious? I've found a small pea sized lump under my arm pit. We're away so I can't get to my GP and I'm freaking out. I've got two little ones and am thinking worst case scenario. It's driving my DH mad as he is very practical and says its probably nothing and I shouldn't jump to dramatic conclusions. I know Dr Google is a terrible plan but I couldn't help it and apparently painless lumps are most likely the most sinister. I'm worried sick.
