I’m not sure what else she has tried and how old she is but it is important to take care of mental health with therapy and possibly antidepressants. She also may benefit from pain management center, occupational and physical therapy guidance on how best to deal with pain and options for treatment (medications, steroid/cortisone shots/bracing and wraps/stretches/tools to use for daily activities, navigating stairs). She should have her spine/hip alignment checked to see if something could help avoid any further issues that could make walking/mobility more difficult. I’m not sure if a chiropractor and/or massage therapist could help release any areas in her spine/hip/thigh that have locked or tightened up. Heat and ice may help with some symptoms plus topical Voltaren gel or nerve pain creams (like lidocaine, CBD or capsaicin). She may be depressed from all of this and could benefit from help supporting and advocating for her if she is willing to receive help.
