After Chickenpox and treatment with Penvir 500, a feeling of heaviness and mild stomach spasms can occur due to temporary digestive upset or a side effect of the medicine. Eat light, easily digestible food, avoid oily/spicy items, and drink plenty of water; you can use a probiotic or a mild antispasmodic if needed. Since there is no pain or constipation, it is usually not serious, but if the heaviness persists beyond a week, worsens, or you develop vomiting or fever, consult a doctor for evaluation.

Severe abdominal pain spreading from the lower middle to both sides and back is not safe to treat at home with medicines alone, as it could be due to serious conditions like Appendicitis, Pancreatitis, or intestinal problems. Do not self-medicate heavily; you may take a mild pain reliever like Paracetamol only if needed, but avoid stronger drugs. Seek urgent medical evaluation immediately, especially if there is vomiting, fever, bloating, or worsening pain, as proper diagnosis and treatment are essential.

Stomach pain with constipation for two days is often due to indigestion, low fiber intake, or dehydration. Drink plenty of warm water, eat fiber-rich foods like fruits, vegetables, and whole grains, and stay physically active. You can take a mild laxative like Lactulose or Isabgol at night to relieve constipation. If pain becomes severe, there is vomiting, blood in stool, or no relief in 2?3 days, consult a doctor promptly.

Severe stomach pain during menstruation for repeated cycles is commonly due to Dysmenorrhea, which happens because of strong uterine contractions. You can use a hot water bag on the lower abdomen, stay hydrated, and take a pain reliever like Ibuprofen if suitable for you. Gentle exercise and avoiding caffeine may also help. If the pain is very intense, worsening, or affecting daily activities, consult a gynecologist to rule out conditions like Endometriosis or other issues.
