So I have been having this certain situation on and off for 8 years now. But lately, started last year, it looks like there's additional other discomfort added in my body. I am talking about my throat. I have this discomfort wherein I always feel the need to remove something from my throat, like phlegm or something. It's not actually painful, it's just annoying. And when I do so, sometimes there's some phlegm that comes out and sometimes, none at all. The phlegm that's coming out is also thicker and stickier than the normal ones we have when we are coughing or something. Right now, my neck is itchy also (as well as below my eyes) and like I said, it's uncomfortable because I feel as if there's something in my throat.
To the other discomforts, well my left arm is tingly and numb at times, especially when I lift it up- my doctor say it might just be frozen shoulder/nerves. And then the other one has to do with my stomach. Two days ago, I woke up feeling full, and when I try to breath (especially standing up) it's kind of painful especially on the upper part of my stomach, right below where the rib cage meets. It was gone after 30 minutes or so. And every time I eat and after, I get paranoid that it might happen again.
What could be wrong with me?
