question: Hi, my mum who is 61 woke yestereday with a large red and black bruise on her let arm, close to the wrist which goes from middle of forearm and wraps inside to quarter of way to inside of arm, it is approx 4 inches long, she cannot remember knocking or hurting it, she was at work previous evening and her job is quite manual. She said it had a burning like feeling yesterday all the way up her arm to the shoulder but no pain - she could use the arm fine. Today the bruise has faded very slightly however in her wrist amongst the veins I can see a lump, is this something she should see her dr for? She has recently had a lot of tests as she lost weight after a family bearevement and cannot regain the weight and is a slight woman anyway but all tests came back clear. Please could you advise me. Thank you
