hello
i can understand your concern
actually the injury has lead to the
soft tissue injury i.e the tissue underneath your skin has been injured,in other words the injury has caused the inflammation of the soft tissue which has lead to pain and swelling---
(1) the most important thing to do is to give rest to the injured part...as feet n ankle bears the whole of the body weight until n unless the injured part gets complete rest for few days the injured part wont get healed so avoid walking or doing any activity for which will put weight of your body on your ankle
(2) lie down in bed in horizontal position for 2-3 days so that the injured tissue get time for healing
(3) do icing for the first 2 days and after that do hot fomentation for 2-3 days few times a day
(4) tie a crap bandage around ankle to restrict unusual movement of the ankle joint n it will also reduce swelling
(5) get a x-ray done of the injured ankle to rule out any minor fracture
(6) take tablet
diclofenac 2 times a day and tablet
serratiopeptidase 10 mg three times a day for 3 days
follow all these and you will be perfectly fine very soon
