I seriously threw my back out for the first time about 15 years ago(about 21-22), and I couldnt move. The ER and normal doctors don't do shit but give you drugs. Don't get me wrong drugs are awesome.
I was lucky and went to one of the best therapists I've ever seen since. He gave me heat + electric + about 60-100 needles of acupuncture, some super mild chiropractic (for the initial injury they usually take chiro pretty easy, but next week and next month a solid regemen of it will do you great). Cannot reccommend accupuncture enough, although IMO 2-3 treatments a year is good - haven't been forever but if I find a doc on the ins. I will hit it for sure.
My back has been completely fucked since then but miraculously that was also the worst it ever "went out".
cycle -ice - heat - ice- on it.
*I am not a doctor but my back is FUCKED and has been for a long time, but it doesnt slow me down. Get good aftermarket insoles at the least, customs orthos if you can, these make a huge difference if you spend any reasonable time on your feet. Good shoes also.
