Hello doctor, My 6 year old daughter has symptoms of having some sort of worms in her stomach. 1. She gets stomach aches frequently, specially while taking her meals. 2. She is usually not eating well. 3. She is often constipated and has a hard stool. 4. She has itching around her anus. 5. She has lately become extremely fond of sweets specially chocolates. Here are my questions: 1. What s the first thing I can do to help her? 2. Are medicines for this available over the counter or are they prescription medicines? 3. How will the doctor test if she has worms? 4. Will some blood test or some other test be conducted to find out what kinds of worms she has?
