Multiple Sclerosis; Need Walking Device

I am raising funds to pay for a BioNess L300 device for a close family member; my sister. Diagnosed with relapsing-remitting Multiple Sclerosis in 2005, she has since developed foot drop. I am a mid-level medical provider; a Physician Assistant. Married to an active duty soldier; I have a family of my own and student loans which unfortunately prevents me from buying one outright myself. This is why I've decided to turn to GoFundMe.
 I only wish Tricia could experience what Jonna Patton, the woman featured in the Today Show clip already has; mobility. I have raised THOUSANDS of dollars walking for MS...only to find out that they are currently "unable" to assist with financial assistance. So I've taken matters into my own hands. I'm doing the fundraising and distributing those funds MYSELF to someone in need. Times are tough...but if you have the means to help it would be greatly appreciated. Insurance will not pay for the system. The total cost is $6200. To just rent one is over $500 per month! I have even looked on eBay to no avail. My family member is a single, middle school teacher on an extremely limited income. Sad isn't it? Other family members have considered drawing on their Social Security early as well as considering cashing in life insurance policies to help as well. They are also assisting financially as this person is having difficulty paying for daily required medications (daily shots; Copaxone) as well as other medications to include Ampyra ("The Walking Pill") to name just a few. Recently insurance determined they were not going to allow continuation with PT as they didn't feel it was indicated. Now having significant difficulty walking I am sickened... As a medical provider, I am disgusted and ashamed of what our government has become with regard to healthcare. If I won the lottery tomorrow, I'd pay for all her required medications, bills and just provide her care. I just can't. The website is www.bioness.com. The device again is the L300 for foot drop. I understand any hesitancy but assure you this is legitimate. I would be happy to answer any questions. Please help if you can. Pay it forward. Don't take your ability to MOVE for granted... Thank you and God Bless. Krista M. Tannery, PA-C, MSPAS
