hehe isn't this a birth control forum?

I don't know I am new at this site

It's pretty easy to read what forum you're on; it's at the top of the page. Birth control gets a lot of attention though; and that's normally why people post here even off topic. I'll move it to an appropriate forum.

thanks Eiri I appreciate you helping me out on my first time.

Well did he feel anything while he was working out? Did he pull something and then he just shrugged it off, "be a man", and continue working out like the idiots we men are? Or was he perfectly fine throughout the entire work out and after, and then he felt it the next morning? Or was there anything else between when he worked out and noticing his pain that may have strained his back (picking up furniture, kids, something)? If it wasn't something he did in between and it was the squats, I'm going to assume he did squats with bar bell (weights)right? I wouldn't take it too seriously unless he is incapable of most movement, he might have simply overworked it or improperly warmed up or poor form. Is your hubby one of those big muscular guys? They tend to never warm up and often have poor form. Warming up properly is vital to prevent injuries. Assuming he isn't like paralyzed on the couch, he might have just pulled it or something, I would tell him to take it easy and do NOT do any back related exercises for some time. Wait it out for maybe 3 - 4 weeks allowing it to heal and observe, if the pain persists even then, THEN go to the doctor. But if it disappears by then, tell him to still wait a week or so even after he thinks the pain is completely gone (just cuz pain isn't there doesn't mean it healed completely), he might just injure it again.

Let us know how things turn out. I would want to know if my advice was flawed.
