Have you always bruised easily? Wondering if you get a bloody nose, does it bleed for a long time? It could be anemia (low iron) and it's best to ask for complete blood work and ask for vitamin D levels. You may as well ask for your thyroid levels as well.

My 9 yr old had an episode of bloody noses last yr. - the problem was they lasted up to 45 min, which is excessive. The doctor did a blood test to see if she had the proper clotting factor....luckily she did. I hope the blood test turns out well and hope you feel better soon.
