Lately, i've had frequent nose bleeds out of nowhere and now my thighs have been purple and covered with smooth red dots for days. any ideas?

Common: 80% of people experience this in their lives. A common cause is dry, hot air like inside the home in the winter causing nasal dryness and crusting. The nasal tissue cracks and bleeds easily. Treatment includes humidification and nasal moisturizing with a variety of nasal saline gels or mist sprays. The petechiae(red dots) on legs raises the concern of a clotting problem that you need to see MD.
