As usual very well said by Bram! I would echo what she said - she gives good advice. I think as women we are so used to being the caregivers to everyone that we guilt ourselves too much.
You are so brave to go through a pregnancy, much less keep after a little one with this horrid disease.
I don't take my own advice on this one very well, but I think to be a good mom and wife you need to MAKE time to take proper care of yourself!
The only thing I can think of it that your O.B. Dr. and Pain Mgt. Dr. need to be in communication with each other about your care.
Bless you!
