My friend has the arm surgery so it made him sore a lot. HE used a bunch of hot icy pads everyday and kept using them more and more to relieve the pains. I heard that cherries are good for joint but it's not for pain relief.

Is there anybody here know any natural herb or food can help to relieve pains? Since the pain killers made his kidney messed up a lot, then it is really important to find to good natural treatment for him.

Thanks a lot!
