Hi, Thanks for writing in. The lumps in your daughter s case look like they are haematoma. This usually occur after some injury. Given the fact that your daughter is anorexic, her tendency of having such a condition increase as the subcutaneous fat (fat under the skin) is decreased in anorexics. This makes them more susceptible to injury. This lump will resolve on its own in a few weeks. There is nothing that you need to do. Hot fomentation will help it resolve faster. Please seek a physician s help for your daughter anorexia. This can have disastrous consequences in the long term. Thanks
