Sick kitten found

I found a kitten beside the road in front of my house. It's making a lot of sad meow sound. When I'd a look at it, the kitten cannot stand, the head keep spinning, and with the sad meow sound. I think the poor kitten might be hit by a car, but there's no blood or any damage at the body. 1. What's with the head hard giggling, almost like a rocker's spinning? 2. Is it only a health problem? The kitten is more than a month. I'm taking the kitten inside the house and it is sleeping. If not, it'll continue that spin and sad meow sound. The road is not a busy one, it's inside our secured neighborhood with fences and security guards. Could anybody tell me how to save it? 'cause my place it's very hard to find a vet. Thank you
