for 6 weeks or longer i have noticed large brusing on my right elbow area.it has gone away briefly then returns. no injury,no pain. it seems to have spread in area-up and down my arm from elbow. in addition i feel extremely exhausted or fatigued(have for much longer)painful joints,no energy, no concentration, and a list of other problems but I wonder if the bruising is yet another symptom of a problem??I am 60 years old, female last doctor visit about year ago.
