If 40 flushes have done nothing for you, I'd say further investigation is a good idea. If it was me in your shoes, I'd go to a licensed doctor of traditional/classical Chinese medicine. Preferably one who speaks English instead of a recent immigrant. These latter are smart but there is a cultural problem sometimes in communication.
Purging (killing worms/flushing/cleanses, etc.) is usually good but it's not always the first thing to try.
