Chronic pain is something you cannot fully understand unless it happens to you, like parenthood.
I took my body for granted my whole life, get cyatica in the back/leg and told my disk is worn down (maybe minor in comparison but it's still debilitating at times to me)
I live in pain or discomfort every single day now. Humans get used to it, it's amazing.
It's not easy, Haggis you have a great sense of humor and share that well and being in pain doesn't make you want to laugh as much, but it helps everyone anyway.
I pay for running around and crawling all over the place too, but for a great game it sure is worth it.
Keep the positive attitude going. I know it's not easy.
