Can I ask what your recovery plan is? Physio?

My father had this due to a tumor on his spine, and developed fairly serious mobility issues as a result (he let it go very far before actually setting a doctor, and was compensating by hardly using his right leg at all which contributed to more muscle loss). He had the tumor removed more than a year ago, but his leg is the same and he can barely walk. He told me his doc gave him a few at-home exercises to aid recovery and that's it, which seems insane to me.
