mystery parasites

Hi all. I was tested for parasites last year and was told I have them, but unidentified as mine aren't in the top 20 list of most common parasites.

My functional medicine doctor told me not to deal with the parasites or candida, as I also was diagnosed with heavy metal toxicity and to address those first.

Now a year later my stomach swelling, noises and gas is so bad after anything I eat, I don't know what to do. I've taken 2 rounds of Paragone, am about to start Black-Walnut , but I don't feel well.

The doctor didn't deal with half my symptoms, just told me not to eat fruit or Sugar or alcohol. Then he made me take liposomal vitamin c which exacerbated my candida cause it had 40% alcohol, which he then admitted was a mistake.

Now I wonder if I should go back to him to get further parasite tests---but I don't want to pay him more money---do you all think I need a specific diagnosis and drug to heal or should I keep taking herbal supplements?

I'm not well. any advice greatly appreciated-thanks
