"I honestly don't know what to do anymore"

I had a pretty dire experience at GRI surgical assessment again. Waited sitting in a corridor to be seen by a doctor. I will say the specialist nurse practitioner was so lovely and took my symptoms seriously and was suggesting different investigations.

Unfortunately the doctor was a different story. No idea what their name was as never introduced themself or had a badge visible (I wonder why). They walked in with what felt like a disinterested attitude and I felt patronised.

I was sent in by my GP with a fever and low oxygen sats, several months of abdominal pain (and pain on touching), nausea and vomiting and over a stone weight loss. I'd been in previously for an endoscopy which didn't find the issue so this time all they did was a chest x-ray and I was sent home on painkillers (that I told the doctor previously caused more pain) and antisickness that they couldn't even give me because pharmacy was closed. They also told me to take a PPI even though they knew I'd had adverse reactions to 4 different PPI drugs. When I reminded them of this, they shrugged and told me that was what they were suggesting. Refused to do more imaging to check gallbladder and pancreas (despite admitting that bloods can often miss these issues) because I'd had a CT scan 5 years ago. I also have a family history of gallstones. We pushed and the best we got was he would do an "urgent" outpatient ultrasound which would take 2 months at least.

They also told me to pick a place where the pain is worse?! And smirked at me the whole way through the conversation, shrugging every time I asked what was I supposed to do if I can't eat due to the pain and vomiting.

I honestly don't know what to do anymore, my Gastro referral is not for another 5 months, I'm going to be so underweight by the time I get seen. I'm so tired of being in pain and vomiting.
