Hello. For loose motions and spasmodic pain, the priority is preventing dehydration. I recommend drinking Oral Rehydration Salts (ORS) dissolved in clean water to restore lost fluids and electrolytes. For the abdominal cramps, an over-the-counter antispasmodic like dicyclomine can help relax your intestinal muscles. Additionally, taking a probiotic supplement can support your gut recovery. Please stick to a bland diet like rice, bananas, and toast, and avoid dairy or spicy foods. Avoid taking anti-diarrheal medications like loperamide if you have a fever or bloody stools. If your symptoms persist for more than 48 hours or worsen, please consult a healthcare professional for a personalized evaluation.

Your symptoms of stomach pain with alternating constipation and loose motions strongly suggest Irritable Bowel Syndrome (IBS). Because your bowel habits alternate, self-medicating with over-the-counter laxatives or anti-diarrheal drugs can worsen the cycle. I highly recommend consulting a healthcare provider for an accurate diagnosis. For temporary relief of stomach cramps, a doctor may prescribe an antispasmodic like Dicyclomine. Meanwhile, try keeping a food diary to identify triggers, stay hydrated, and manage stress. Please seek immediate medical care if you experience 'red flag' symptoms like blood in your stool, fever, or unexplained weight loss.
