You should ask your doctor what the cost will be. If you are paying out of pocket, they would be the very ones to tell you how much it will cost. Also, many times, paying cash gets you a discount... they don't have to spend the time and staff to deal with insurance, they don't have to wait to be paid, etc.
Not too long ago, a friend called me to ask me to drive her to the doctor. She was vomitting explosively. Everyone in the waiting room moved as far away from us as possible.
LOL It got funny (well, to everyone except my friend) after a while.
If I can go with THAT friend to the doc, surely one of your friends will go with you to a laser treatment. Find one that needs to catch up on her reading. She doesn't need an exam room, just a comfy chair.
