This is incredible - I nearly teared up, to be honest.
I'm 19 1/2 years old, and I have had this issue for at least five years. Sometimes it is one side, sometimes it is both sides at once. It feels swollen, and it is whenever I am anxious, however I still always believe it is an infection, or cancer, or something of that nature. I feel it subsiding as I am typing this because it is like the confirmation I needed, telling me it is just in my head.
Stress and anxiety do the strangest things to our bodies, and make us feel so "strange," for lack of a better word. I know this, yet I am so obsessive, I have the most trouble believing I am not ill, and it is in fact just anxiety or an effect of stress.
I know it is just stress. And I know it's terrifying when it flares up, but it is just an effect of this awful illness.
