I have had a history with weak lungs and my doctor before told me I had them. A thing I had before to know I had weak lungs was that my eye would be red, it s somehow closely tied to that. But this time it s different, my eye keeps tearing up and the redness usually subsides and goes back and a thing is that it always produces that eye gunk that you get after waking up in the morning. Is it possible that it s sore eyes though it s just one eye? I m torn because if it s the thing I had before it would always just be red and the redness would not weaken if not subside. I really need your help.
