HiT hanks for your thereafter going through your query I came to know that you had injury below knee last night. It seems to me soft tissue injury (sprain). X-ray may be done to exclude fracture. Putting ice is OK. You should not use it till it pains. Splint can be used to rest it. Leg should be keep elevated on pillow to reduce swelling. Analgesic such as diclofenac will be of use for pain. You can take vitamin B-complex and C to promote healing. You can discuss with your treating Doctor about it. Hope your query get answered.
