I'm going to suggest reading chapter 4 of this:
The Science of Getting Rich - Wikisource
Read other chapters as well, but apply what it says about disease in chapter 4
Remember you can't get rid of a condition by focusing on the condition, even if it's to get rid of the condition. Instead, focus on there being no condition at all... Reguardless of appearences, you are in perfect health... Hold the thought of being in perfect health, and allow the condition to remove its self from your reality...
Hope this helps...
