Self-healing - just the presence
If pain is perceived as the absence of your attention, then the remedy must be your presence. There is a simple and beautiful self-healing meditation technique that channels your 'presence' into the diseased limb. It is definitely a better option than painkillers, whose side-effects sometimes prove worse than the original complaint!
A meditation technique:
Let us say that you have limb pain. Lie down in a dark room. Make a conscious effort to forget about your whole body, focusing only on the part which is causing you pain. As you experience your painful limb, deliberately drop the word 'pain' from your mind.
Your mental chatter will continue to tell you that you feel pain. Switch it off. Feel deeply; experience with an open mind. Look into what is happening inside your mind. You will soon see that your mind was just exaggerating the pain. Put all your awareness on the center of the pain, and it will soon shrink to become just a tiny pinpoint of pain. Concentrate completely on this point, and you will discover in a sudden moment that the pain has disappeared, and in its place is pleasure, bliss.
