Hi, I'm hoping for my mind to be put at ease.  For several months I had dizziness and throat issues.  Small bits of food sticking around in my throat.  I could drink milk and burp a few minuits later and feel the coldness of the milk half way down my throat like theres a pocket where food hangs around in.  

There would be an on and off tight/restricted/lump in the throat feeling.  Ruling out globus sensation as when clearing throat, coughing or burping I could little bits of food moving up and down the throat.  

I swallowed a chip whole one night and I'm sure it stuck around at the back of my throat for about a week as I could feel it moving up and down.  It went down eventually.  After that, I got a period where I had a strangling sensation in my throat.  I was also extremely dizzy.  Doctors referred me for an endoscopy and said that there was wax in my ears that could be causing the dizziness.  I'm worried I might have Esophageal cancer or something bad.  For the several months I had these issues, I have frequently cleared throat bringing up sputum regularly.  Sometimes I couldn't tell if an ache was in my throat or ears.  Occasional chest pain and palpitations but I am 18 stone.  

A doctor felt my neck thoroughly with his fingers and checked the back of my throat and saw no anomalies (would these checks detect a tumour?) Allthough the doctor gave me a leaflet on globus sensation, I Suspected GERD, was given omeprazole and the dizziness and throat symptoms improved after a few weeks.  On the 19th June, a lymph node on the right side of my neck had become swollen and red.  I saw the doctor about it the next morning.  He inspected my throat and said that the tonsils looked a bit red and noticed my swollen lymph node.  He prescribed me flucloxcillin and ive been taking them for 3 days now and it has got slightly bigger.  It is sore and red.  I don't feel otherwise unwell, slightly dizzy.  I also noticed that the node is hot to the touch.  I was told if it doesnt improve in 48 hours, to phone the doctors which I will do on Monday as they were closed on saturday.  Only one lymph node is swollen.  

Is there any connection between my symptoms improving and a lymph node becoming swollen and is there anything about what I've described which might point to my issue being non cancerous please.
