Diamond shape/honeycomb branding on my skin

[Xoxoalii]

i need answers asap! No dermatologist nor doctor can figure out where these are coming from. I woke up yesterday morning with a branding underneath my left butt cheek on my hind thigh. It is not raised, not itchy, does not hurt, it looks literally like a branding and is exactly in a perfect row of diamonds 6 X 7 pattern. It looks as if I sat on an iron chair and the imprint was left on me. I have not changed anything in my diet, not changed anything with my detergent. There is no explanation. I did read a lot and do lots of research and the only thing I can find in common is people saying they got these "markings" the next day after watching something about ufo's or had weird vivid dreams the night before these appeard! And the night before these appeared on me I was watching a show on alien abductions. Can anyone help or have any connections?!

I don't have an answer but I started with hives about a month and a half ago.  I have been receiving Ultraviolet therapy for them twice a week.  The diamond like pattern was present then but now it just is hives and itching that moves around my body.  I took a course of prednisone but finished it 4 days ago.  I had a treatment with UV this morning and am miserable right now.  I took antihistamine but not helping.  BTW I love Ancient Aliens and watch it at least 4 times a week.
