Hi there, thanks in advance for any advice answers, I hav a large bruise that has appeared on my arm, I DO NOT bruise easily, as an example I once fell down a flight of marble stairs and only had a very very small bruise, I don t remember injuring myself and its large dark and has a raised white centre, I have no signs of sickness, dizziness or fatigue or any other symptoms for that matter. It worries me due to the fact I very rarely bruise, again thank you for any advice as I do not have time to visit my local GP
