1. Let the patient rest the injured part in the most
   comfortableposition, slightly raised if possible.
2. Cover the affected area with a cold compress for
   approximately 30 minutes.

3. Then remove the compress and cover it with a thick pad.
4. The strain or sprain needs rest and support in the form of firm
    bandage. Start well below the damaged joint and firmly warp a
    bandage around it, leaving strips of padding visible. An elastic
    bandage is best, but it should not be tight as it may damage the
    underlying nerves and blood vessels. If any part of the limb
    becomes cold, numb or puffy, after application of bandage, it
    means it is tight.
5. If pain is severe, but there is clearly no other injury, the patient
    can take paracetamol. If the pain seams too serves and in all
    doubtful cases, Rush him to the nearest hospital.
