Discomfort and feeling food stuck behind chest

I am male and 50 years old. I have had issues with globus sensation since February this year. About five years ago I had my first bout of globus. I was drinking a lot of coffee, morning, noon and night and noticed this choking feeling in my throat. I looked it up online and took a two week course of esomeprazole. This cleared it up (alongside stopping the coffee drinking permanently).

Fast forward to last December, and I had chest pains after my evening meal. I then had, over successive days, a feeling of chest pains after that radiated along my left arm. I was scared enough that I took my self to the hospital in early January. They did an ecg, blood tests etc. and everything was normal.

Then in February, the globus sensation came back. I put myself on some omeprazole and after a week of no improvement, decided to go to the doctor. She said it sounds like Gerd and to keep on taking the omeprazole but twice daily. This didn’t fully help. So i suggested to the doctor that esomeprazole helped me in the past and so I switched to that again. It didn’t fully help either. Then I noticed that taking Gaviscon Advance after meals and before bed seemed to alleviate the symptoms more. I also use a wedge pillow and have limited my diet considerably, so much so that I have lost 30lbs in two months. I recently started experiencing an ache between my shoulder blades when eating.

In the past month I noticed that it is painful eating certain food like bread, potatoes, and dry food. I am ok swallowing, but with those types of food it feels like they are taking ages to travel down my esophagus and it feels sore when they do. I haven’t regurgitated anything yet. I went to my doctor over a week ago and asked for an endoscopy, but he put me on a non-urgent referral which can take over two months before my appointment. I am extremely worried about cancer. I have also noticed tenderness in the epigastric region but this could also be due to not eating much. I know the likelihood of cancer is low, but I am constantly scared that it is, especially with the chest pain when eating solid food.
