The first big question is allergic reactions, and is the body reacting to something in the diet? Gluten? Try buying rye bread its actually inexpensive from a McGavins Bread basket. Diet pop? GIANT NO NO! Milk? Some people cannot digest it well, I have a friend who bloats massively if she ingests milk products, with all the discomforts.

The last time my stomach went rock hard was in a hospital from 4 litres of blood trapped inbetween the intestines from a ruptured spleen.

Again I don't and cannot give medical advice. The question remains *why* is it rock hard. I would suspect as well the immune system is attacking something in there causing swelling over time.

Its not a lot of information to really go on, I would really recommend for myself in that situation a Master Cleanse and see what comes up (out!) Basically its lemon, real maple syrup, and cayenne pepper - mixed and drank as long as your comfortable. For at least a good week. Myself I'm not a fan of the straight cleanse because its lacking in nutrtition somewhat and I would supplement with at least some salad, or fruit once a day to keep energy levels up.

Another trick is to start hitting the cinnamon. Take a couple tablespoons mix in a protein drink and bottoms up. I find in yogurt its strong, and in porridge its strong (at two tablespoons) but in a protein mix it tastes great, and goes down easy.

Cinnamon is extremely antiseptic. Studies have show it clears out ecoli, and a various multitude of bugs from the colon and is recognized as a strong colon cleanse.

Interestingly here is an article combining a master cleanse with cinnamon
