Re: back pain and feeling sick
I can relate to what you're saying.
I sometimes feel nausea when my back is acting up.
Other times if I feel my back is unstable or "catching" and twinging, I will feel my stomach has butterflies in it sorta. I think that's what you're describing.
I have had my butt go numb and stinging and i'm sure it's a pinched nerve.
Sometimes ice helps, and stretching exercises. I try to do a daily routine and keep myself from having any acute episodes.
I have spondylolithesis, and pars defect, as well as bulging disk and arthritis, so it's tough at times.
You're not alone though and hope you feel better soon.
