GI symptoms: See a doctor. Your symptoms may be related if you have contracted a parasite. You will nee to have your stool tested to determine the type of worm and get the appropriate treatment.

Sure could!: If you are passing worms in your stool, that may mean you have a lot more inside roaming around. Enough to make you sick. Please get checked for what kind it could be and get treated. Always wash hands after going to the bathroom and handling pets or food. Don't share those little worm eggs or pieces! It is not better to give than to receive when it involves worms and their eggs!
