It's acid reflux. Note carefully when you eat a lot, or quickly gulp down a snack or drink, and you'll see it worsens after those events.
Keep water with you at all times and sip it. Also, chewing gum is a miracle treatment that will slow down your throat clearing, because it makes you swallow regularly. Finally, begin to train yourself to eat slowly, chew more, and don't eat crap like nachos or hot dogs without lots and lots of water. I've also found that beer can trigger this problem, just stop drinking it. you'll live, and live better.
HI Ryan,
Your symptoms could be tons of things. I don't think it is in your head or a nervous tick. Please go to a Gastroenterologist to check you for acid reflux. Yes, you can take something over the counter and you might experience some relief. However, acid reflux, if this is what you have, should be taken seriously because (untreated) it can lead to stomach/esophageal cancer.
Please see a Doctor.
Nervous tics. Trust me,
I know!!!
It sounds like some of it could be due to a habit of clearing your throat. I know sometimes I will do that and then keep doing it and before you know it, I feel like I constantly have something is my throat. Also, could be some inflammation, have you asked your doctor about this?
