symptoms are headache chronic fatigue confusion or lack of focus abdominal pain ... they go on and on and are different for different people. if you SEE mold, get out. at least find out what KIND it is. mold can lead to MANY MANY different complications in the body including scarring on the brain! candida and mold go hand in hand so i bet you probably DO have it if you suspect it? who knows though. until you have numbers from an established source it's all guesswork and that's more stressful than anything. mold leads to SERIOUS complications and illnesses !
that worm is a parasite from surfing in dirty water or eating a horrible burrito after i got out of the water. i found that i had those when i did a hydro colonic therapy session. not what you want to see floating in the toilet at all.
