Anyone ever had G.E.R.D? (Reflux Disease) and Did you ever experience a lump in your throat?

I’m struggling to swallow without feeling this big lump inside my oesophagus and it’s sometimes painful. It’s near the base of my throat (neck) on the left hand side.

I am currently under my doctor and am on Esomeprazole to treat it (40mg). However, I have been on this medication now for 6 months and it’s supposed to have cleared up but is getting worse. I’m due to go back to the doctor a week next Tuesday but wondered if any of my fellow jellies had ever experienced this before? And even if you haven’t if you can give me some kind words to stop me being so neurotic about this… I feel like my body is falling apart at the moment. :-(
