Answer:
What you need is you test to see if you really have them. Bloating, stomach cramps, increased appetite and brittle hair, constipation... these are all symptoms. If you have some of these symptoms, see a doctor right away.
If you have worms and these need treating the doctor will administer a treatment called a vermifuge, which will kill the parasites for you. However there may be other things you have to do to prevent becoming re-infected.
Pills can be administered to treat the worms. Be sure to ask about the worm's eggs, too. They can lay over a million eggs in a single lifetime AND STAY.
