Hello i am 15 years old and I have been getting sharp pains on my left hand, my bones ache all day and i don't know why. I don't use my left hand for anything i don't type much, what could it be ? I also been getting really strong headaches. It happens at least 4 times a week and the pains are everywhere on my head.I also haven't been in any accidents or injured myself anywhere. Please help, and thank you.
