You can do an average amount of walking, such as around the house, after getting an ankle tattoo, but it will be painful. It's best to avoid exercise for a couple of days to give your skin a chance to heal and for any swelling to go down. Avoid shoes that will rub on the design, and keep your hydration levels up to prevent fluid retention. If you're worried about driving, take a friend to the session who can drive you home. Lastly, always remember to practice proper aftercare to avoid infections and speed up the healing.
