Congrats on the decision.
If you are hard and fast over this doctor - then you need to talk to them or save the money.
Banks aren't doing personal loans like they used to and for a non-essential procedure - they will most likely deny.
DO NOT apply for another loan -it will lower your credit score. If you belong to a credit union, then talk to them. They are a tad more lenient in lending terms and conditions.
If you can't do that - then either wait and save the money or ask a family member. If you own your home - consider taking a 2nd out for things and use the points as a tax write off.
GOOD LUCK!
