Had two scopes done, first found an insignificant hiatal hernia, second found nothing at all. For the past month I feel as though there is a lump in my throat. I get up in the moring feeling fine, within an hour the lump is there, it usually last until early afternoon. By the time I go to bed it is gone. I have been sleeping fine and not walking up with a sore throat, etc. I do not burp after eating or have heartburn or chest pains.....any idea of the cause of this lump? My thinking is that the hiatal hernia has gotten larger, but wouldn't I have additional symptoms?
