Few Questions

Hi shelley, few questions

Why is it every time I eat something with soy sauce, I get pimples? but not with salt

I've been on a candida diet with coconut oil and probiotics for three weeks, then I started to have a dripping nose at the end of the third week, its very watery, then few days later I ate a cake then it started to get stickier, then after two days, it's gone. What does it mean? and then I realize that my digestion is getting stronger because I have less gas nowadays and it only occur now in the morning, but after I go to the toilet, it's gone.

Why does everytime I lie down on bed after I ate, I hear some bubbling noise from my stomach then in my gut then an hour later I release few gas. Then when I lie again, it's like I feel the acids in my stomach but no more gas.

I also don't know if I have candida, because my only symptoms are: some rashes on elbows, dandruff, watery eyes, flatulence, some white things/skin peeling around my mouth, at first I thought it's because of dryness of the skin, and there's also in my belly button, my nose is always dirty as well as my ears.

and is it also common for a teenager to have these? what is the cause of this?
