Issues with goni after using fluconazole

[kilnakorr]

My goni has been retracted since I did a fluconazole treatment. It was the only coral that even reacted, and I thought it just got a little angry.
This was about 2 months ago, and it still doesn't open op. Polyps are barely peaking out every morning, then retracts again after a few hours.
Any ideas on what I can try, to help it recover?

Did you do some big water changes after the treatment?

It,s been several waterchanges since.
I also run AWC, so plenty of water has been replaced.
It is possible something else happened, but would be a strange coincident.
