Neck Pain Treatment

Im 17 Years Old And I Consider Myself Quite Healthy. There's Just One Issue. If I Stand, Walk, Or Even Sit For A Long Period Of Time, Say An Hour, I Get This Sharp Burning Pain In My Neck. It Goes Away Within A Few Minutes But It Comes Back. Could It Have Something To Do With My Posture? Can It Be Related To A Pinched Nerve Or Maybe Its Something With My Discs? Please Help!
