Well.....after a ton of research and question-asking, I'm 99% convinced my chest pain is a partially-collapsed lung. It can be caused by numerous things, but I think the thing that did it for me was sleeping for too long on one side. (I slept for around 10-11 hours one day last week on my right side, and if I remember correctly the first time I recall having the pain was immediately after I woke up.) Although I'm no doctor, I read it can be remedied by doing lots of deep-breathing exercises. I hope it works. I'm still a bit short of breath, but the pain went from a really sharp stabbing pain to more of a very dull annoyance when I inhale.
As for my eye, I'm still in the dark about it. (Sorry.....bad joke.) What I do know is that I think it's nothing too serious because my eyelid won't open all the way, kind of like it's an infection or something. I don't think it's pink eye (ewwww
) because it's not itchy or red.
Jeez....I'm a complete mess. Both health-wise, financially, emotionally.......
I wanna thank you guys for being so nice.
I'm a freak when it comes to worrying about complications due to diabetes, and that has the hallmarks of just such a complication.
