Need a second opinion

[coelio]

Hello,

I'm a 30-year-old woman, and I'm sorry to ask my question on this forum, but I need a second opinion.

I've been having yellow and light brown diarrhoea for three weeks and for just over a week I've had severe back pain (middle/upper back, central and left) and I sometimes have pain under the solar plexus and the left ribs. Sometimes I feel nauseous.

I've had a general abdominal scan three weeks ago and an ultrasound, both of which are normal. I'd like to have an MRI to make sure I don't miss any lesions/tumours, but my doctor doesn't see the point.

Do you think I should insist?
