How do you get rid of pain from a finger thatvgot slammed in a door?

If your finger or any part of the body suffers from pain due to a minor injury (only in case there is no wound but just swelling and pain and no fracture) then you can follow the following method: warm oil in a pan but do not over heat it, then put some onion and warm them up as well but do not allow them to become red then add a little amount of turmeric to it. Apply this to the area which is paining. This will surely reduce the pain and give relief.
