My husband has had 2 brain surgeries in the past 7 years to remove a meningioma on the top center of his brain. He had a round of radiation after both surgeries. He has recovered remarkably well except that his left leg is sometimes numb in certain places and tends to turn inward (had rehab after surgery to correct it significantly), making walking a bit of a challenge. He does not use a cane. My question is; would massaging the leg before he gets out of bed be a good thing, and what specific exercises could he do to improve his mobility?
