Finger swelling and arm discomfort after botched cannula for CT scan

A few weeks ago, I was meant to have a CT urogram with contrast dye and furosomide (a diuretic) but neither the nurse nor radiologist could get my cannula in properly. They were trying at the inner elbow. The nurse tried both arms then the radiologist took over. He put it in the first vein the nurse tried as it's the only one that sticks out a bit, but it already didn't work when the nurse did it so I don't know why he bothered.
The radiologist then thought it was in place but I could tell he wasn't confident. It was really quite painful and I was very uncomfortable and stressed. He flushed it anyway and went ahead with the furosomide. I got this horrible burning hot sensation that went down my arm to my hand and nowhere else. I told him and he panicked, pulled it out and there was discussion about whether he accidentally put it in an artery. At this point, I really panicked and said I didn't want to proceed any further. They decided it didn't go in an artery but maybe went in to the soft tissue. They logged it as an incident (datix) as well.

God knows what he did but the furosomide still worked as I was peeing all the time and it also lowered my blood pressure and later in the day I was dehydrated. When I'd calmed down a bit they said I could have the scan without the contrast dye, so we did that.

However, since then, I've not been able to sleep on my right side (the side it was in) as my index and middle fingers swell up a bit and my hand and arm feel really uncomfortable. The gp said things like this can happen to the lymphatic system after trauma and it should hopefully resolve itself but it doesn't seem to be getting any better. I'm now wondering if they damaged the vein or some other part of my arm. The gp said if it doesn't resolve she'll refer me to the vascular team. I'm not sure how long to wait though, I'm not seeing her again until the end of the month. She also said my circulation seems fine. There's nothing visibly wrong unless I've been sleeping on my right.

I also have a problem with my neck and shoulder (stiff, tight, achy) on that side that's been there a while and is also getting worse so I'm also not sure if it's perhaps coincidence and something to do with that or if it is a vascular / lymphatic thing to do with the cannula, or maybe it's both.

Has anyone else ever had something like this happen? I usually sleep on my right side but now if I do it's so uncomfortable and keeps me awake at night.

That doesn’t sound right so I’d call your GP for an appointment or contact the hospital dept where your procedure was carried out for advice, today.

@CleanSkin i initially went to urgent care to get checked out straight after and they were saying everything looked fine, bloods were fine etc. And I've seen the gp since then, about a week ago and she said that it can happen trauma to an area. Do you think it's really worth calling again today?

Your best bet is to speak to the department who put in the cannula so they can assess if there’s anything to worry about - they’re the ones that will have recorded the procedure/the drugs/know what anatomy they were close too/what they think actually happened. There are several possibilities that might explain what you’re feeling and no one here’s going to be able to suggest any really useful ideas.

@Greybeardy thanks, unfortunately they're just radiologists so not medically trained as such. I will call them though.

They also said on the day that they may have hit a nerve but it seem like they don't really know what actually happened, they were a bit useless really.

Radiologists are specialist doctors. You need to speak to yours (not a radiographer operating the equipment- also highly trained, but not a dr)

Greybeardy · 03/09/2026 11:38

Radiologists are doctors. Both radiologists and radiographers are usually very good at getting cannulas in. They’re also really good at working out what’s happened when things don’t go to plan and can help with deciding if any further imaging is needed to work out what’s happening. I’d go back to that department and ask their advice.

RealLifeClanger · 03/09/2026 15:12

That was just what I was told on the day, that they're not medically trained. Maybe it was a radiographer that said that. I'm waiting for a call back from them anyway.

I just spoke to a radiographer and they said to go to the gp, so I'll book an appointment tomorrow. Hopefully it's nothing too sinister.

Good decision. How are you feeling now?

@CleanSkin I saw a nurse practitioner who said it was likely nerve damage. Hopefully it should sort itself out eventually. It's better than it was but it keeps coming and going. I'm sleeping with my arm on a pillow now, which seems to be helping with the swelling a bit.

Thanks for the update (sorry for the slow reply). Glad things were improving & I hope they’re continuing to do so.
