Life changing treatment

This is my sister AnaCary.  She was diagnosed with cervical/lumbar/thoracic radiculopathy stenosis. Prior to being diagnosed with this she was hard working, did everything she could and more for my nephew. She was independent, strong, loving, caring. She always put others before herself.  She’s only 30 and is now unable to stand or sit for longer  than 15 minutes increments. She’s been to more than 20 doctors trying to find a cure for her and she finally found a treatment that has been helping her. However the insurance company is not covering this treatment  and it costs $6000 and since she hasn’t been able to work in over 2 years  it’s been hard to get the money for her to continue with her treatment. She’s already had 2 surgeries and they have been unsuccessful, multiple epidurals and therapy. She’s also taken pain medications which in the end didn’t help and have caused her to loose 80lbs.  So I’m asking for everyone’s help in getting her back to doing simple tasks like sitting and walking for longer than 15 minutes. Any little bit helps.
