Hi,
Welcome to health care magic,
Lower
abdominal pain with alternate
constipation or diarrhea is not normal but should be evaluated further by appropriate tests.You should seek urgent medical attention but need not to get panicked.
It could have many causes which are
acute colitis or
genitourinary infection since you also have left testicular swelling.
You should undergo routine blood investigations and liver function tests,urinalysis and abdominal ultrasound and colonoscopy to detect exact the underlying cause.
Treatment is mainly depend on the cause but she may take symptomatic treatment meanwhile.
Antacids like h2 blockers (ranitidine) or proton pump inhibitors (
pantoprazole or rabeprazole) will help to reduce excess acid production in stomach.
Apart from medications she should eat plain foods like boiled rice and green leafy vegetables without adding spices or oil.
It will help to neutralize digestive acids and also they are easily digestible means there will be no need of extra stomach acid.avoid oily,spicy and fast food.
Take optimum quantity of laxatives to avoid diarrhea related to it.
Consult your operating/treating surgeon or gastroenterologist for detailed medical history and clinical examination to diagnose the cause.
Thanks and Regards,
