Gray stool. Really scared...

So I went to the toilet in the morning and I’ve made a habit of checking down there to make sure there’s no blood and noticed that half of my stool was light grey. I freaked out. I’ve never in my life had grey coloured stools. 

Other symptoms I have:

Burning and pain in my chest and shortness of breath

Nausea after certain foods

My stool keeps changing colour and for the past few days it’s been yellow (half yellow, half grey today)

I had to pass a stool multiple times yesterday. I wouldn’t call it diarrhoea as I didn’t feel like I had to rush to the toilet but it would just happen every time I had to pee. The stool would be yellow and quite chunky but loose.

I had abdominal pain for 2 weeks about 2 weeks ago and it would hurt at the sides of my navel, in my ribs or hip bones after eating.

I am going to see a doctor on the 15th. I hope that’s not too late. I’m so scared I have a tumour or have to have my gallbladder removed. Or cancer. Idk I’m thinking about the worst.

On a side note, I have Gilbert’s syndrome.

Gilbert’s may be causing your stools to be yellow

Why all the worries. Don't guess about your condition. Wait until you get checked out. Ok you will be fine.
