Donn is right: your body has new things to work on this time around.
Heartburn caused by gas and aching limbs sometimes with pain and other discomforts....................
Gas: Many patients have considerable intestinal gas while fasting. Those who suffer with digestive troubles, visceroptosis, colitis, enteritis, etc., and "nervous" patients are most likely to be troubled with gas. In not a few cases there is sufficient gas to cause distress, even sleeplessness. Most of these cases experience difficulty in expelling the gas.
In most cases, distress is probably not due to the presence of a large amount of gas, for this is seldom present in large amounts. It seems rather to be due to increased internal tension. A constant internal tension or pressure is maintained in the digestive tube. This is regulated by the sympathetic nervous system. Increased tension is felt, reflexly, as pain or discomfort in the muscles of the abdomen.
"Nervousness," shock, strong emotions, etc., may cause increased tension in the tube and the faster will experience some kind of discomfort. Subconscious fears also may cause the so-called gas pains. Those who have long suffered with digestive derangements are especially prone to changes in the internal tension of the tube.
Functional irregularities in the stomach and intestine may cause pain because of increased peristaltic contractions that often exist in these. Marked visceroptosis, with sharp angulations, may increase the internal tension and cause discomfort or pain.
Increased peristaltic activity of the stomach walls, due to "nervousness," may also result in discomfort that is mistaken for "gas pains." Increased tension may occur in any section of the tube and thus pain or discomfort may be either general over the abdomen or may be more or less localized.
Fasters who so suffer generally complain that the "gas" makes them nervous and keeps them awake at night. It seems that the opposite of this is the truth--the nervousness causes the increased tension and resulting discomfort. Where these patients are able to completely relax, their "gas pains" cease. Although I no longer employ any of these: suggestion, abdominal massage, hot water applications to the abdomen, a drink of warm water and other measures, will usually relieve this distress, at least temporarily without actually lessening the amount of gas.
Gas rumblings in the intestine mean unstable nerve control of this organ. Cathartic drugs will almost always produce these rumblings. This is due to excitement produced by the irritating drugs.
The gurgling and rumbling often heard in the abdomen is due to the movement of gas from one section of the intestine to another. It may often be due to emotional interference with the normal sympathetic control of the gut. A nervous patient may exhibit such rumbling on the slightest provocation. Enemas, due to the excitement they occasion, often produce these symptoms.
Aching Limbs: Besides pains in the back, usually in the lower spine, there frequently develop in the early days of the fast, pains in the hips, pains at the base of the skull and aching in the limbs, particularly in the joints. These pains and aches are often very annoying, but seldom last more than one or two days. They develop chiefly at night and cease during the day...........................
