Difficulty swallowing out of the blue
so i am 13M and yesterday i had salmon for dinner. Halfway through the meal, I felt like i was just physically in able to swallow solid foods, blamed it on the fact that i was full and moved on. Today's breakfast i had this same feeling and after about 5 bites of painful chewing, i started to worry. I stopped and told my family about this, but they just blamed it on the fact that i was full, its psychological, or my growth spurt ended. I had lunch, same problem, couldnt swallow anything. Same with dinner. At this point I am seriously starving, and I know im not full, quite the opposite actually. I cant swallow food anymore, but drinks go down just fine. I also noticed that I have much less saliva in my mouth, and I have dry lips. I am scared I am going to end up losing weight soon even though im already skinny and die from no food or smth. Pls help im scared for my well being. also keep in mind that this has never happened to me before. it genuinely feels like the moment i look at food, my brain forgets how to swallow, and i immediately gag. Thanks.
