You didnt get to specific about
neck PAIN , which is more than general discomfort to most people- so I'm not sure of your degree of pain.
That said, like the last poster, standard old school chiros that just crack you is not that effective on tight muscles. Active Realease Technique is great, (ART dot com) will lead you to a practisioner that does this. They are usually younger new school chiros that have expanded there schooling beyond just cracking. Look it up, it works.
