For as long as I can remember, occasionally air would come up my throat and make a weird sound. But lately it has been happening often, like every 10 minutes. When I breathe in sometimes, something that feels like air will come up my throat and make a weird sound. It doesn't hurt or anything when it does, its just weird. I'm not sure if this is normal or not. I just want to be certain its not anything serious. It often is worse after eating. Thanks for the help.
