I used to collect cactus(cacti) as a kid and have gotten those little spines in my fingers, and they hurt a bunch. I can only imagine how much pain this person must be in, and they will find those spines for a long time to come. Ouch! Ouch! Ouch! Not funny. 4::22yikes::cus::crew:
I have been there. Not a barrell cactus as that appears to be, but I did crash and roll over a fallen Saghuaro Cactus in my youth. You know you have a true friend when they will pull cactus needles out of your butt for over an hour. Damn that hurt.
Actually that's Cholla cactus or otherwise known as jumping cactus. The spines leave quite a burning after effect once removed. barrel cactus has curved spines like fishhooks and that can be a whole different problem. I had my time with those as a child.
