R., I am so sorry that you are in pain....I agree that you can go to Parkland - it's not exactly free but they will see you and treat you regardless of your ability to pay. You will receive bills - make no mistake - health care is never free but you can pay this bills in small amounts over time - even if just $20/month. Now I want to address something you mentioned that you may be needing. The MRI with contrast. Let me warn you to be EXTREMELY CAREFUL and make sure your doctor understands that you are struggling with renal healthiness. My son spent 99 days in the hospital after batteling for his life with MRSA septic shock. Because of the illness, he had renal failure that thank God was only temporary. My son needed an MRI as well but after agonizing over the decision, his very wise and "on the ball" attending doctors decided the risk was too great. Apparently, there are recorded cases where the dye that is used is extremely harmful to patients who are compromised renally. I know you are not in kidney failure but I would surely say that you could be "compromised" with all of the recurring infections you've had. Bryce's doctor said the dye can cause calcium deposits on the skin that are debilitating and permanent and with him, they were not willing to risk it so he and a nuclear bone scan instead. I usually don't take much time to respond in this long of a matter but I am on this one because I want you (and your doctor) to be very safe with your health. Please, please, please, if you do find yourself being prescribed the dye contrast MRI, ASK IF THERE ARE ANY POTENTIAL PROBLEMS BECAUSE OF YOUR RENAL COMPLICATIONS.
Again, Parkland is an option, but be prepared to be there for many, many, many hours just waiting. If you go, bring something to keep you busy while you wait.
Hope you find some answers and get some relief,
