I don't know if this will help, but there is a structural difference between my right gum, where no fluid comes out, and the left gum, where fluid comes out.

My top left gum did not heal like my right gum. The only way i can describe it as is my gum is smooth and then sinks down into a soft, crater like pocket above the last two molars. It is not firm behind this part of the gum but squishy. The pocket is is covered with healthy skin, so from the surface it looks like normal gum except with an abnormal ending. My top right gum is smooth and firm like bone all the way back to my last molar.

I've pointed it out to the oral surgeons I have seen, but they don't pay much attention to it. They jut say my gum healed weird, but I think it is contributing to the fluid coming out.
