Sorry - I'm not able to help, but just replying to bump it up again and hopefully somebody else may be able to assist.

Just quickly - have you been feeling stressed lately? I was stressed at work once and my eye started playing up. Saw a specialist and there was nothing wrong. Just stress. I think it can do really weird things to our bodies. Especially if you have just started to relax AFTER a stressful time in your life. Just as an aside - we adopted a kitten from a shelter once and a week or two after we had him home, he came down with cat flu. Took him back to the shelter as they covered vet stuff for a period of time after adoption and they said that it was really common for the animals to come down with stuff once they were out of the shelter and really stressful environment and feeling a bit safer again. bang. THey then got sick, so just wondering if something similar was happening for you?

I'm also a big believer in the body coming out in symptoms when we are ignoring other things in our life, something out of kilter, or staying in a job or r/ship for too long that makes us miserable, not speaking up for myself (I ALWAYS get sore throats when I don't speak up for myself) etc.
I'm not sure if you've ever tried acupuncture before? Might be worth a go.
Anyway, I hope it clears up for you soon
