giardia- what is your pain like? Relieved by garlic?

I'm trying to figure out if giardia is what I have... my stool test came up negative but I'm suspicious! Anyone who has tried natural remedies like grapefruit seed extract, garlic, or neem tea -- how well did these work, and how fast did they work? I am wondering if I can conclude that I have giardia based on a good response to them. Also, what is the abdominal pain from giardia typically like? I have read that it is usually just above the navel (whereas mine is just below). If you have been diagnosed with giardia, could you comment on what the pain was like, where it was, and whether it changed after you went to the bathroom? Tweet
