Just found this recipe list of a cook who has cured his own acid reflux. I know it's not the Tietze o Costochondritis related, but after researching the web, his recipes are the same what we should eat.
I am planning on trying some out.
Also, just found that if your in pain try singing along to your favourite song. Try a song that moves your fills your chest with air. I find it's a very good way of exercising your ribs. I found Sterophonics' "Maybe Tomorrow" works well.
Plus, it's a good song. =D
