@BlackFriYay im sorry to see you’re having swallowing problems. I’ve got experience of both sides of that coin - I had trouble swallowing and the feeling of a lump which I had an endoscopy for. This was a truly horrible procedure without sedation so if they offer it to you, bloody well have it! The results were clear; a combination of reflux and anxiety. The anxiety part came from a close relative who had the same but the outcome was the complete opposite :(
I find now I’m on MJ that I have trouble swallowing cheese. Everything else is fine, but cheese just does not want to shift 🤷♀️ Your GP has to rule out anything sinister happening and I’m really glad that they are taking you seriously. If you aren’t already, you could get some omeprazole over the counter and see if that makes a difference while you are waiting for the camera.
Most people who need to have the scopes find that their problems come from reflux or hiatus hernias, both of which are very easily treatable, often with nothing more than twice daily omeprazole. The percentage of people who do have unfavourable outcomes is very small.
I know only too well how much easier said than done it is, but please try not to worry about it, and bloody well stay off Google 🤣
