Here are the following things you could try
1.Reflexology over the hands and feet to find out where there is pain and therefore a problem in the related organ/s http://www.susanna-riviere.co.uk/diagram.html
2.Go to an acupressure/naturopath for a diagnosis.
3.Cleanse the body (Colon Kidneys and Liver). Methods available on this site.
4.Try a spiritual practise like Pranayama and thus rise above the current situation, transcending the body itself. http://www.pranayama.org/Merchant2/merchant.mvc?Screen=CTGY&Categor...
5. Lastly, eating a non irritant vegetarian based diet.
These are my suggestions which have worked for me in my own healing. I can't say how much they will help your specific condition, but they are universally helpful in my opinion.
All the very best.
