In your first post you mentioned that you have had all-day headaches, with spikes. We kind of ignored that, but as you raise this I think you might want to consider the possibility that you might have a CH "lookalike" condition, some form of hemicrania. Hemicranias typically do not respond well to oxygen or triptans, but I gather that you have not really tried either one yet. You don't really fit into any of the specific hemicrania categories, but you can see the symptoms of one type here: https://www.ninds.nih.gov/health-information/disorders/hemicrania-continua#:~:text=What is hemicrania continua%3F,both sides of the head.
It could be/is most likely that you have CH and you are experiencing what are called "shadows," but what you describe seems like it might be more than shadows. In the document I keep urging you to read -- https://clusterbusters.org/forums/topic/6213-basic-non-busting-information/ -- there is a discussion of shadows and things you might do to alleviate them.
