I'm 17 years old, and for the past few months I have been waking up with bruises on my legs and arms. Lately it has been getting worse. This morning I counted ten. The last a couple days like any bruise but I don't recall injuring myself in any way. Also I have been getting a stinging/burning in my finger tips has only happened a couple times. Using know if they are related in any way. Please help me figure out what might be wrong.
