Sometimes have a sensation of heaviness, pressure, and suffocation on my neck. usually happens when i sit. is this normal?

LegendOfSleepySwallo: First, see or feel anything on the outside? Swelling? Lumps?Next, how's your posture?Head up,chin parallel to the floor?Neck held relatively straight, chin back a little?Are you significantly overweight? Snore as lot? Daytime sleepy?Suffer from heartburn?Nervousness or anxiety?I'd go see a doctor if this persists longer than a month or it's getting worse.An ENT doctor would be a good start
