my daughter has a lump (size of 2 golf balls) under her armpit, a red line running from it down her arm. The lump has been there for 3 days. Yesterday (Friday) a doctor looked at it - briefly - and gave her antibiotics, but didn't do a thorough examination, even when she told him that for quite a while, she has had a feeling like "a grain of rice tied to a piece of thread is being pulled through her breast". I live 3,000km away from her and can not be there with her, so I am finding it quite distressing not knowing what the cause is, or diagnosis.
