Hi, I Believe I Have Giardia. About A Month Ago

Question : Hi, I believe I have Giardia. About a month ago I ate a meal in XXXXXXX and both me and a friend got extremely sick from it (throwing up). I was continuously sick for the next couple of days (diarrhea) that I decided to cancel my trip to come home and just get healthy. When I got home and had my first meal, I became sick again (threw up) and had diarrhea again for a couple days. Since then I have been taking probiotics and things have improved a little. However, I still get stomach cramps and when I go to the bathroom, it is often just unloading a lot of built up gas and when there is stool there it is soft and greasy. It has been a month and my symptoms still persist and aren't getting any better. From talking with others who have traveled through XXXXXXX this is a common bacteria that they pick up. I spoke with a local pharmacist and she recommends Flagyl (Metronidazole) but needs a prescription. She said she does take prescriptions from WebMD. I don't currently have health insurance, but out of pocket she said it would only cost $11. I am hoping you an provide her with a prescription. I can pay what I need to here out of pocket if you can provide a prescription. Please advise.
