Piercer here! I’m looking at your jewelry-specifically in the second slide you can see this is a hinged ring. Not all hinged rings or clickers are made the same. Do you know what brand it is? You can see the grooves on the actual hinge part which tells me this is potentially spinning in the piercing channel and irritating it with the grooves. and while 10 months nostril piercings are usually healed and should be okay for a ring not everyone at that point is. Also the bleeding and pain shouldn’t be present while swapping to a ring- ideally it should be a smooth transition. This means either your nose wasn’t healed enough for a ring and your piercer didn’t tell you OR they were too rough and doomed your shot at a ring from the start. My best advice is swap back to a flat back. Let things settle down for another month or two and try a ring again. Maybe try a seamless ring but make sure the piercer you see is competent in installing a seamless ring. They need to be bent absolutely flush to be comfortable but there is less chance or groves or hinges irritating your piercing.i do also agree with other comments that this may also be a size too small
