Hi, I woke up one morning with left arm numbness from the elbow down with hand weakness and wrist drop. My doctor ordered a head CT and neck MRI to rule out anything life threatening. It turned out to be Saturday night palsy. How long to recover?

Palsy. Even though the initial nerve damage is serious, the palsy generally heals within several weeks. Treatment involves resting the injured nerve often by wearing a splint. I believe that a neurologist should direct your care and dictate when to start proper physical therapy.
