So had my CT Angio yesterday.
Contrast was a strange sensation. Got the metallic taste which stuck with me all day, then nausea and warmness and felt like I'd wet myself. Afterwards had quite a lot of pain in backs of my lower legs and strangely in my left side radiating upwards from my man sphere. Radiologist didn't seem concerned and once my BP came back up (was like 90/60) sent me on my way.
Now it's waiting game for cardiology. They said expect to hear something within 2 weeks. Fingers crossed no blockages!
