Vagus Nerve

First off, any help or answers I can get would be very appriciated, so thank you. So, For the past 100 days I've been having multiple symptoms that are becoming very taxing and doctors don't know what to make of the problem anymore. The only reason I know exactly how long this has been going on is because it started the night after I decided to take a break from partying/drinking etc. The list of symptoms I have varys from constant nausea, sweating palms, trembling to hearing my heart in my left ear. Origianlly my doctors thought this was anxiety/withdrawral, but the symptoms have persisted for months. They recently have mentioned that there might be something wrong with my digestive tract and vagus nerve connection or possibly an obstruction in the form of a polyp. Has anyone heard or seen this? I just want my nausea to go away, any help would be appriciated.
