Rozie's Medical Expenses

Important please read!
My best friend is Rosanna Saffaie Cuellar and she suffers and battles every day for her life with this horrible disease that is unknown and misunderstood called CRPS/RSD. It stands for complex regional pain syndrome/regional sympathetic dystrophy and is known to be the most medically painful disease in medical history.  Every day she fights and tries so hard to do the simple things in life. Most days she can barely get out of bed or leave the house. She can't sit, travel, walk well, or do things on her own and much more . The disease has spread to her whole body and she is battling so hard and having so much pain trying to find a way to fight! Its unbearable and difficult for us whom love her and know her to witness her pain and struggle and how little quality and capability she has in her life. But She fights! This disease has no cure and people don't understand that it spreads not only to all extremities but it also can spread in their internal organs. It is painful, it is crippling, and YES it's life-threatening. Also nicknamed "the suicide disease". This disease makes people feel like acid run through their veins and that their burning alive. Stabbing, swelling, stiffness and brutal pain all constantly with no rest. If she's lucky, she sleeps an hour. The rest of the time is a constant struggle to try and move into a position that doesn't make her want to rip her hair out. She's 5'5" and is only 103 pounds due to the stress of constant excruciating pain. 
Most doctors aren't sure what to do with her. She was hospitalized for 4 days and then her insurance stopped paying so against the advisement of 5 doctors, she had to go back home and depend on her husband to try and take care of her. She is on a ton of different medications which are barely helping. Her husband lost his job because he has to take care of her 24/7 so they have no money coming in at all. Their rent went up over $300/mo at the beginning of the year and her poor husband got in a car accident and they can't even afford a new car so he borrows one from family members when he can. Credit cards are maxed out... You get the point. They are such humble, hard-working people. The last thing they want to do is ask people for money so now we've stepped in to ask everyone to pitch in.
Her best chance right now is to go in for nerve blocks. There is only one doctor we know of that can do a specific technique that will minimize the chances of making her worse. Unfortunately, her insurance does not cover this doctor so she has to come up with $1800 up front in cash in 2 weeks just for the 1st procedure. If she gets any benefit from it, she will have to do many many more. All of which having to pay $1800 up front in cash before she can be treated. They only have one more week to come up with $1625 for rent plus the expense of food, medication, you name it!
