I agree with both of you to some degree but I'm with Aconita that we shouldn't have to feel pain and it means something is wrong for sure. What I think is wrong is that I've been walking upright and using my back for 42 years (43 tomorrow). I think age has worn down the disks but more so there's a lot of inflammation that began back in my heavy weight lifting days.
Wait, your birthday is on 420? Haha, well of course there's sour diesel for lower back pain, and it fucking rocks for pain. Medicinal marijuana, yes yes yes. But there are side effects, and of course sweet mother plants aren't really curing what ails you. She's just masking the pain, she might be more fun than boring ole ibuprofen, but I still think that modern otc pharmaceutical anti-inflammatories are pretty fucking great. Here's an instance -- ibuprofen -- of a drug that actually works (at treating symptoms). Yet "treating symptoms" is sometimes really good because it teaches the brain to stop sending stupid pain signals to areas of the body where no defect exists to cause pain. I'm back to saying pain in the body is often learned response.
And happy birthday! Birthday on 420 makes you one of the cool kids.
