Blood under one's toe nail

Q: My toe was hit by a heavy thing falling down and it caused some blood to emerge within the nail. I heard that blood on the surface was pure and I washed the toe and did not think about it. Weeks later I thought about this again when I saw the dried up blood in my nail (Note: some of the blood was within my nail so I cannot remove it, otherwise I would need to remove my nail!) and I don’t know if that counts as pure or impure. 

Continuous discharge

Q: I have a wetness problem. There is no feeling of discharging wetness nor does it flow on my leg or clothes. There is always little wetness by my private part, almost 90% of the time. Whenever I pray and after completing prayers I check and there is wetness. What is the ruling for me?

Do I have to check everytime and then make wuzu again and again? Do I need to break the salah if wetness is felt, it might be water as well since we do istinja before wuzu and offer namaz immediately. I dont break my salah, rather I complete my salah in this condition, am I doing something wrong? I am not sure whether I am a mazoor or not.
