I have a pretty severe case if fibromyalgia, and complex ptsd. Not many strains alleviate my pain... just lessens the pain. Same goes for my complex ptsd. However, I picked up some Hell's OG from my local dispensary on a whim, and I couldn't be happier. I had been in a sever fibro-flare for 4 days, and this stuff almost fully alleviated my pain. I'm still shocked. And the level of calmness that I feel from this strain is absolutely amazing. I am usually irritable, pissed off, and on edge. Usually I need something very heavy for my ptsd(such as afghani), but then I'm couchlocked, and not very functional....Hells OG calmed me just as much as a really heavy indica, yet I can still function, or sleep. I also enjoy the very earthy, yet subtle flavors. To sum it up, GREAT for pain & ptsd...calming yet still functional, and taste great.
