I can certainly understand yours and Lysha's frustration! We put so much faith in our doctor's only to have some of them let us down. Tell her to hang in there, go ahead and go to your appt. on the 31st. It can't hurt. She needs to be blunt with the doc and tell them all that has been going on. Help her make a list and go over each symptom. Tell them of your frustration with this last doctor and their lack of time spent with her.
I'm really sorry and I hope you have answers really soon. Sometimes we have to press on even when we don't feel like it, but it's then that we can look back and see we have traveled far thru the troubles and tribulations and we are stronger and more compassionate people.
