3 adjectives to describe sprain

Fearing that he had sustained some injury more than a mere sprain, Lawrence had had the Howlett's doctor summoned, and that general practitioner had come and gone, after having assured Mr Croft that no bones had been broken; that Mrs Keswick's treatment was exactly what it should be, and that all that was necessary for him was to remain quiet for a few days, and be very careful not to use the injured ankle.
