That sucks!
Do you have any friends in the area who could possibly recommend another OB/GYN to go to?
Maybe the specialist will be good and have a recommendation.
Most of my doctors I have been seeing for 15 or more years...because I like them and their staff. I lucked out about 5 years back when I started seeing a new Rheumatologist. He us really great. He actually recommended the doctor I see for my RSD (he does Physical medicine, rehabilitation and pain management).
I'm sorry you are having to deal with this. Try and do your best to rest and relax while you are off. Of course we all know easier said than done!
