Hello, Home remedies like hit formentation will definitely help you. But my advise to you to meet a Physiotherapist asap. As stiffness after cast is bit obvious and it can be removed only via mobilization of joint which a specialized Physiotherapist can do. Need not worry about it. It can corrected with proper Rehabilitation.

Put a foot in a bucket filled with warm water and move your ankle in circles 2-3 times in a day. Keep doing ankle exercises throughout the day. This will help in reducing stiffness. Consult a nearby Physiotherapist for a proper treatment and Home exercise program. Thank you

Stiffness is normal after the cast is removed, and to get full range and strength back physiotherapy is highly recommended. At home apply hot pack few times a day, stretch ankle muscles as much as possible , and move your foot as much as possible in sitting, walk as much as possible to improve foot coordination.
