Im afraid there's something wrong with my mom :(?

she kept getting these little bruises about five at a time on her arms then they would show up on her legs and other areas of the body and the bruises start to fade then come back. Then i kept telling her to go to the doctors and she said well then that leads to more trips to the doctor and i don't have time for that. This was about a month ago when the bruises started randomly appearing and now she feels very tired and she went to the doctors a couple days ago bc she felt so bad and now we're waiting for her blood results to come back. I just don't know what could be wrong wih her?
