Looking for PCP in AUSTIN

Hopefully someone can help me. I am new to Austin.  I had the DS surgery.  I cant even find a PCP that knows what a DS is.  I brang him a list of labs that I needed and he was just like you dont need all of that. He said this after admitting he has no idea what a DS is. Any DS patients out there with a good PCP here in Austin? I need someone that knows what a DS is.    I dont feel safe with the PCPs I have seen here.  

Thank you
