5 weeks now. I went to OS few days ago as I was getting a sharp needle pain occasionally for a few days and had milky white discharge for about a week or so. No foul smell or anything so the discharge wasn't bothering me until needle pain came so thought I would let him check it out.
He said no infection and not to worry about the discharge. The needle pain he said was the sinus membrane repairing itself. My next appointment is in a week and if it hasn't closed them will go ahead with P.R.G.F.
Gum wasn't as red as it was last time and he said there is granulation tissue, though there was an indentation in the gum.

He put my mind at rest so that was great as I am a naturally born worrier.

I have noticed it is healing but not closed yet. The other day I thought it was closed but then when I did my daily inner mouth photo (yeah I know, a bit geeky and obsessed) there was a bit of food stuck in there blocking the hole. Out with the salt water gentle rinse.

Hope it heals by next week, that would be
