Question about Daredevil

Why is it that in 'Daredevil', after Elektra stabs him in the shoulder, he is seemingly too badly hurt to go to her aid, but he has no problem at all swinging across the city, fighting Bullseye, swinging off again and fighting Kingpin? All the time, he should be losing blood and getting weaker and weaker.

Some hero eh? She's better off without him.

Because 'Daredevil' was a terrible movie where they screwed up everything you can possibly think of.

He used his heat vision to cauterize the wound, then with his rapid healing factor and powers of flight based off of the radiation from our yellow sun, he swung into action against injustice, and corny lines delivered by Colin Farrel "bring on the pain, bring on the noise!" okay, Mr. House of Pain. Tell all your moms, I came to drop bombs.
