Detailed Answer:
Hi,
Thanks for query.

As per your query answers are:

Yes the pain is most likely a referred pain from the abdomen
I am suggesting you a few medications which are very effective in diarrhea.

Dicyclomine is an anticholinergic drug. An anticholinergic agent is a substance that blocks the neurotransmitter acetylcholine in the central and the peripheral nervous system. Anticholinergics inhibit parasympathetic nerve impulses by selectively blocking the binding of the neurotransmitter acetylcholine to its receptor in nerve cells.

Mebeverine is an antispasmodic medicine and is very useful in IBS and is well tolerated by the patient with minimal side effects.Mebeverine works on certain muscles in the wall of your intestines, causing them to relax. This eases the pain and cramps. Can easily be combined with dicyclomine.

Clidinium bromide is an anticholinergic (specifically a muscarinic antagonist) drug. It may help symptoms of cramping.It is much more selective then dicyclomine and is used specifically to treat spasm in IBS. Usually, 2.5mg is given in combination with 10mg dicyclomine.

Chlordiazepoxide works by increasing the action of GABA, a chemical messenger which suppresses the abnormal and excessive activity of the nerve cells in the brain. Can be used in combination with above-mentioned medicines.

Diphenoxylate and Atropine combination(Lomotil)-Atropine/diphenoxylate is an antidiarrheal and anticholinergic combination. It is an excellent antispasmodic it also prolong the time it takes to move the contents through the body.

So my recommendation is instead of loading her with heavy doses of single salt of medicines give her a combination of two to three salts in low doses.

Food pattern recommended is-

Eat simple and natural home cooked food.

If possible try detox diet(Raw vegans) for at least 3 months. Take normal food in lunch while in supper take the uncooked raw natural form of food. This can play wonders.

Avoid taking excessive fibers. A total fiber intake of about 20-30 grams per day would be good for you. Any thing in excess is good for nothing.

No pizza, Burger, Red meat, and dairies for few weeks.
No alcohol or smoking (if at all do).

Take natural food rich in probiotics like Yoghurt, Kimchi, etc.This does not mean that you have to take them as much as you can. Just follow your body increase their uptake gradually.

Drink lots of juices and fresh water daily.
Avoid over spicy and heavy food.

If possible go for a detox diet but again don't force your body rather let your body adopt gradually to things.

Whats the salt in Bezytyl and chalazal? Please mention the salt name so that I can give you further advice.

Regards.
