Yikes. Is he in a medical office building? You might want to see if there's another p-doc in his building. Then you can just explain the situation to him- it may cost you an extra visit but at least you'll get the treatment you need.

Or you could try another p-doc office- explain that your doctor is out office and provide his number to verify that he can't be reached- and they may be able to take you in for a last minute appointment.

As a last resort- you may want to bring your prescriptions either to your primary doc or an urgent care- and see if they can give you a partial re-fill to last until your p-doc comes back.

Good luck! Sorry you have to go through this.
