In order to keep my mom at home, we need her to stand with assistance to change her, etc. She is in a wheelchair. We know the stem cell injection won't enable her to walk again, but the doctor suggested it might help with the arthritis pain when she has to stand with assistance for a very brief time. The injection is very expensive and not covered by insurance, so we are not sure if this is a good decision. Also, are there safety concerns? Any advice is appreciated.
