Question : For the last 5 days I've been getting unusual stool colours varying from brown to green and just recently grey.

I had some initial nausea on day 1 with vomiting and pain in my lower left back.

I am taking Panadine Forte pain killers, just recently started dex amphetamine at 30mg daily for ADHD.

I'm a 45 year old male . Never smoked. I drink alcohol.

Brief Answer:
Get stool occult blood test done

Detailed Answer:
Hello,
I have gone through the description you have provided.
Have you noticed dark yellow coloured urine during the last 5 days. If yes then you would need a liver function test to look for jaundice.

I would suggest you get a stool test for occult blood. In case the test is negative the in wouldn't worry about the changing colour of the stools
Hope this helps
Do get back in case you have further queries
Regards
Dr Samir Patl
