Unexplained bruising all over body, fatigue, wieghtloss, headaches, loss of appitite, body aches, mild dizziness, weak legs.what going on with me?

Worrisome: The symptoms you describe are very worrisome, in particular I am concerned about possible cancer. I would see a physician ASAP and get some blood work drawn to check counts and other labs.

Something of concern: We get questions about "a bruise" all the time...those are not this much of an issue: Generalized bruising Weight loss The other symptoms are hard to characterize (body aches/weakness/mild dizzy) since very common and usually from minor things. The degree of both of the concerning symptoms I cannot tell without an exam for your situation. but deep/bloody bruising worse but exam/tests regardles
