Re: Core exercises for a broken back?
I suffer from constant back problems. Degenerative, collapsed, prolapsed, you name it. Just a mess.
So one of the most important things you can do is regain mobility and refrain from reinjury. The pool PT is great, it is the only thing I can really do to the point I get smoked. Every other exercise leaves me in pain before I get winded. So treading water in the deep end wound up being my thing. You can add weights when you get a little more practice, they'll drag you down making you work harder.
Quit for the day if you feel the nerve pain, like shooting or burning streaks of pain that go down the leg. Or if it gets worse or moves down the leg.
Short walks around the 'hood help.
There are some floor exercises too, it would behoove you to ask your back doc, PT, whoever, to go over them with you. They are way too difficult to explain online (nearly impossible in person --how to explain how to use muscles you don't "feel" or know exist!?) These are the muscles you inquire about, and the exercises aren't intuitive and you will likely need instruction to do it right. One thing you can do is crunches, but not a full crunch. You are mainly laying there and just flexing those muscles. If you can, flex the ones below those.
A chiropractor can be good, but I just spoke to my back doc and she said not to do it, for me anyway. I have nerve damage caused by my spine and she said it is risky to set or reset a back when nerve damage is present. Some really good chiros will she said, some won't, and it all comes down to them knowing their limitations. Something to look into, but if you have nerve damage, ie, shooting pains going down your legs, perhaps it would be best to forego the chiro.
Again, what that guy said about GO TO THE DOCTOR, DO IT! Don't trust online suggestions with your back, your health. My back doc just told me that a chiropractor could have paralyzed me, not ten minutes ago, had I went that suggested route. Your doc will know what is good and what is bad. Hopefully.
You pain meds can get you through tough times, but beware that they can also trick you into doing more than your body is ready for, thus setting you back. Sometimes months. Be careful, try to use the pain meds to relax at the end of the day and to get good rest. Don't use 'em to push yourself harder.
Good luck, back problems SUCK! Stay away from surgeries until the last minute, long story short, it usually gets worse after surgery, not better.
Oh yeah, if you are or do end up on opioid or opiate painkillers for a while, 6 months or longer, you may need to take testosterone injections too. The opiates reduce your testosterone and in addition to making you "less of a man" it makes you feel crappy and wound down too. Just a heads up, blood test will find out, but many doctors are clueless about the fact that long term opiates will kill testosterone production in the male patient.
Good luck, get better!
