dude my docs are the same way, unless the test comes back positive they will not just give out worm or parasite meds. And it makes me very upset when I hear people on here say they went to the doc and got the med without an issue,just told them the symptoms..
You might want to try one of those drug protocols listed above, I was suppose but havent grown the balls yet to take meds from other countries and/or animal meds which a lot of people take here and some with good results..anyways good luck.. we are all in this battle together!!!
