Hyper sensitivity after a stroke?

My sister-in-law suffered two strokes (one to each side of her brain) about a month and a half ago. It effected her vision and fine motor skills among other things. Yet the most curious thing seems to have happened -- she complains about pain and discomfort even from a minor touch from someone else. She is now home and my wife is adding her recovery and therapy. In simply brushing up against her while helping her get dressed, her sister thought she was being scratched. She had physical therapy today and complains that the belt they use (to help in case she losses her balance) is injuring her. Is this a possible after effect of strokes, or could there be another explanation?
