Hi, Thanks for writing in. Lipoma is a benign tumor and not a serious concern. It is hoped that your suspected lipoma was sent to pathological laboratory and confirmed to be lipoma which is a benign fat containing tumor. A lipoma is easy to operate on and the entire tumor is excised. The ankle is a complex part of anatomy and contains lots of small muscles and ligaments. Such an operation can take 4 to 6 weeks to give you back your normal strength and range of movements at the ankle joint. The ankle is a joint which is used a lot and is among the most important joints for locomotion. You might get in touch with a rehabilitation clinic and start doing physiotherapy exercises. Please keep your operated ankle over a pillow when you lie down to sleep. Getting heat and cold pack will also help. Application of ointments will reduce any dull pain that is present. Please do not worry.
