Hi everyone, as the title says I am rescuing a Blackneck Garter Snake that was found in a residential area and was planned to be killed so I decided to keep it.

The reason I post this is because I noticed that it have a wound in his head, it bleed when she tried to eat a pinkie and she didn't ate it.
I also have noticed that it doesn't flick it's tongue and when it opened it's mouth I saw what I think it was its tongue but it apeared like it is stuck in the tongue sheath it only looked like a needle coming out a little.

Can someone please help me?

Regards.
