Hi I'm hoping someone can help me.. I have a really sore right arm from shoulder, underneath but only when I put my arm back.. I lifted my arm and noticed I have 2 lumps (swollen lymph nodes I'm assuming) I have no other pain my breast ( although I do have implants) appear normal and nothing has changed but I'm worried about the pain in my arm and lumps under my arm.. I'm so worried as my sister is a Breast Cancer survivor and don't think I could deal with anything going wrong.. I'm a single parent too.. just need some advice please I'm so scared I have cancer xx
