Hello there friend.
I had some problems with my digestive system, stomack and intestines. I seek help with an ayurvedic doctor, and I think you should do the same. Even if you have some knowledge with the books (like me, I read a lot about ayurveda) your not an specialist on the area.
With the doctor I really discovered what was my problem, and now that I´m treating it I´m much better, something like 90% better.
bye... namaste!
