Jesus frucklestick christ!
Don't wait til Friday, I would run your behind up to the hospital NOW and demand that they do something!
My boss had this exact same scenario; he ended up with a massive infection and sepsis and it was a huge goddang deal. He ended up in the hospital and it was a mess. If you "pinch" the infection into the bloodstream, well, that's what sepsis is and you just don't want to deal with it. GO NOW!
If antibiotics haven't worked for
three months do something else!
Oh my goodness, I am inflamed at the incompetency of your dentist! Please do something now, and then keep in touch with that lawyer, and let us know what happened! Don't put your health secondary to anytthing else; hell, go to the ER.
Best of luck!
