It is not diabetes. There is a pro fighting game (Guilty Gear and Street Fighter) player called Marn that has HS Purpura. Is causes the blood vessels in your skin to get inflamed and bleed, and there was probably a secondary infection happening at the same time.
Whang! on YouTube has a pretty good video where he looks into this and gives more details
I know a dude who's legs are purple from the knees down. He weighs around 400 pounds, slams sugar all the time, and doesn't care.
I am not friends with him; his personality and lack of self care as well as caring for himself, despite having a wife, kids, and parents who love him are beyond the limits of my compassion. At some point I feel like we have to take ownership of our own lives and at least try.
Before I get swarmed with responses about depression, how hard is it, etc., he has a massive support group. Every time he gets more assistance, he accepts it and just continues as he is.
No, it's full proof! Scientific papers are always saying how the type and cause of everyone's depression is exactly the same. That's why any primary care specialist, psychiatrist, psychologist, or counselor will tell you to save your time and money on medication, therapy, diet, exercise, relationships, and self love, and to focus exclusively on eating liver. Still feel low? You're not eating enough liver!
My daughter has HSP and it looks nothing like that. The dots are red for her, and bigger. I'm sure it's possible to present differently, but man that looks so much worse.
Yeah, I get autoimmune vasculitis from time to time when I have a rheumatoid arthritis flare up and it looks very similar to this (although mine is never this bad because I take meds, like holy shit that guy must be in ridiculous amounts of pain and needs to get on some medication right fuckin now)
