I am in Rhode Island, but I went into the Foundation for Peripheral Neuropathy website which has neurologists familiar with peripheral neuropathy listed by state. Texas has a number of listings. While FPN does not endorse these doctors, they are a place to start your research there. Best of luck in finding a good neurologist to treat you and get you some relief!
