I did something a few months ago and pulled something in my back. Went to the doctor when the pain hadn't gone after a few days and it was exactly as described. He made me do a few movements until i triggered it, then told me i had lumbago, take some painkillers. I got home and googled lumbago, which basically told me I had back pain.
(As a side note I had some kratom, which worked wonderfully for this, better than the ibuprofen I was prescribed. Fortunately my pain went away after a few days, but I see that the DEA wants to ban kratom in the US. That would be pretty bad for many who use it for chronic pain).
My understanding of the kratom situation is that the worst danger is how it's all too easy for it to become habitual. I absolutely do not think it ought to be banned (nor any psychoactive plant for that matter), but interested parties should be forewarned.
Many advocates may only use it occasionally and/or in consistently low doses, but there are plenty of accounts out there of users ramping up dosage and then having a really hard time getting off it. Withdrawals from heavy use read a lot like similar accounts of kicking a Vicodin habit.
Agreed, I subscribe to some kratom subreddits and some people do seem a bit irresponsible with their use. And after two or three weeks of daily use I could see it getting addictive. Though it wasn't hard to cut back on at all, but I wasn't using particularly high amounts.
