I'm sorry that nobody has answered your question yet.
Depending on what type of insurance you have, they may provide medical transportation depending on your level (if any) of disability and your individual situation. This is especially true for insurance coverage through Medicare and Medicaid.
If these options are not available to you, there is a pretty wide network of public transportation available all over the Dallas Fort Worth metroplex. You can also speak with your dialysis center to see if they are aware of any additional options for transportation.
Hope this helps, and if there is anything that I can do to assist you in real estate, please don't hesitate to contact me.
It's more than real estate. It's RAYL-Estate!
