I believe my 4-year-old daughter has worms... Pinworms... Should I see a doctor or can I go to the pharmacy?

Yes, if you suspect that your 4-year-old daughter has pinworms, it is advisable to see a doctor or visit a pharmacy. The pharmacist can provide treatment for the whole household based on their weight. To confirm the presence of pinworms, you can use a flashlight to check near the anus during sleep or at night. It is also possible to see the worms in your daughter's stool. Remember, it is always better to seek professional advice when dealing with potential parasitic infections.
