Any advice or insight? My 84 y.o. mom has rheumatoid arthritis and hip/back pain. We’re managing it but she’s now getting symptoms of foot drop: right ankle/foot is numb or tingling, can’t much move her toes, and difficulty lifting her foot while walking. We’ve been to her rheumatologist and spine doc, but they only suggest a cortisone or pain shot. Can anything else be done? I’m hoping for suggestions for therapy, if only to prevent it from getting worse.
