Having trouble eating..

For about 2 weeks now I’ve been having trouble swallowing my food I feel like it gets stuck or I’m choking so I basically try to chew my food till it’s liquified. So I haven’t been eating as much as I used to and I have been loosing some weight . I also get like an uncomfortable feeling in my upper back like right between the shoulder blades and I’ve also been experiencing some pain in between my breasts. I’m planning to call to make an appointment to get seen they are just always booked at my doctor, and I don’t want to spend hours at the ER so I might have to wait a little to get seen at my doctor. I just wanna know if anyone else has experienced this before or might have ideas of what it sounds like ? Thanks in advance.
