Lingering coughing, 2 months now?

[PB96]

So.. I've been dealing with some other health issues, cysts in my thyroid gland, myoclonic jerks and twitching (the latter might just be BFS).
But I've noticed over the past couple of months that I've been coughing a lot. I didn't feel sick at first. Then om holiday, I felt really bad, with vomitting and so on, and coughed frequently. I got better, didn't went away completely, then came back a few weeks ago. Got better, now beginning to worsen again.
I don't feel ill, an according to doctor's tests, no infection. But some clear or yellow phlegm do come up sometimes.

So why do I keep coughing more or less? I'm beginning to worry a bit.

You should probably have your eyes checked sometime soon. You are on the EYE FORUM.   Sounds like you need to see your personal physician soon.

Oh, and I don't smoke, never have.
But I had chest pain (left side) a few weeks ago during the same time, my coughing got worse again. The chest pain has vanished though.
