So sad. I've seen that too in some family members. I've learn to trust the medical community less and less. Best to do research and try alternatives if they are available.
Chiropractor warned me of possible outcomes if I tried surgery. What really made me go to chiropractor happened when I was seven and grandparents had me go with them to visit old couple in desert. The man lived sort of primitive but had a spring he got water from and a large pond. I got bored with his canoe on the pond and tagged behind him in the garden while he gathered some veggies. His back was strangely stiff like a board and he explained how repeated surgery and a metal plate made him that way and he regretted listening to doctors.
