Hi, Welcome to health care magic, For constipation you should take symptomatic treatment. Take plenty of water, foods like vegetables, fruits, and leafy vegetables on every day as it will make stool bulky and soft by retaining water in it leading to easy passage of stool. Take syrup lactulose or cremaffin plus 3 TSF at a bed time to have soft and effortless bowel motions in the morning. So, you should also take antacids like pantoprazole or esomeprazole (Nexium) before half an hour of meal with digestive enzymes (Unienzyme) which are available over the counter. Take pain killers (paracetamol) if there is unbearable pain but it must be taken with antacids as I suggested. Take digene liquid or ulcero-protective agents like sucralfate or bismuth subsallicylate if you have the burning sensation or fullness in stomach. Itching could be due to drug induced or some skin problem like dermatitis or fungal infection. You should take oral anti-fungal drugs once dosage with topical corticosteroids to be applied locally twice daily. But before that you must consult dermatologist for further examination and complete treatment. Regards,
