In Naruto Shippuden, Sakura heals Hinata in episode 169. After Hinata is beaten by Pain, Naruto starts changing into the Nine Tails. Pain and Naruto move further away from where Hinata was beaten. Neji, Tenten, Lee, and Guy find her down on the ground and take her to Sakura. Then Sakura heals her wounds which weren't fatal. She then wakes up later.
Hinata fights the Pains in episode 166 of Naruto Shippuden! it is alos the episode where she confesses her love to Naruto.
Naruto Shippuden episode 97, The Labyrinth of Distorted Reflection
Episode 190 in naruto,pre-shippuden,but still in the first naruto series. It's in the filler episodes
Hinata tries to fight Pain in episode 166 of the "Naruto Shippuden" series. She confronts Pain to protect Naruto and shows great bravery despite knowing the overwhelming power of her opponent.
Neji and Hinata do not fight in Shippuden. Shippuden is the second part of Naruto after a 3 year time jump. I think it's episode 46-47 of Naruto (without the Shippuden). Since the time jump they have been getting along a lot better and it's been revealed that they fight together now as "comrades" according to Hinata's father, Hiashi. Also, there are hints of an unrequited affection from Neji towards Hinata. Hinata, of course, still love Naruto. However, it's clear to see that Neji is no longer harboring hatred for Hinata. Therefore, NO MORE FIGHTS! They do train together though.
