stem cell for multiple sclerosis

I have had multiple sclerosis for 20 years now and have managed to live a normal life until approximately 7 years ago when my walking started to get worse. I currently work full-time as a bookeeper and have never missed a day but I now use a walker to get to and from as my legs have grown weak. I refuse to take the MS medications currently available as I have heard more than enough negative reviews. I am usually a very active individual who likes to help others in need but have been limited due to the progression of this disease. I have heard plenty of good things about the stem cell procedure helping MS patients live a better quality of life. I would love to see if this procedure works for somebody in my shoes so I may have a testimony that can help others who are going through the same struggles. I am mostly bound to my home now, afraid of going out in public most of the time, I would love to attempt to have at least a portion of my life back so I can continue to help others in need, not be a burden to others and do the simple things I was able to do before like going for a walk down my street or playing with my nieces and nephews.
