Hi! It sounds like you have pinworms! I would look into each and find out your preference! :D And make sure that they ship to you.
I like Humaworm because we have tried it. It is gentle and effective, however it does seem to be a slow cleanse. We are on our second cleanse and are doing really well. I have read from others that it might be a good idea to rotate between companies to make sure parasites to do not grow resistant to whatever formula you are using. This is something we have been thinking about.
Good luck to you!! Let us know how you are doing!
I would suggest keep reading, keep doing your research and find which one you like more. :D
