you may have jabbed the sciatic nerve, but you would have felt that immediately when the needle went in.
You may have inflammation reaction from the BA thats compressing your sciatic nerve. Whatever the case, you definitely have compression to the nerve, be it from the needle, inflammation, or disc bulge.
This is what you need to do:
get your chiropractor to do an ortho-neuro exam, as well as a sensory exam for your lower extremities. Tell him in those words. If he looks like he dosnt know what you're talking about, find another chiropractor. Basically, he should perform a bunch of orthopedic tests on you, and he/she should also test your sensitivity to sharp and light touch along all your dermatomes, using a little pinwheel or toothpick, and some cotton wool. Pretty standard sensory exam. BUT IT HAS TO BE DONE RIGHT!
If you do not have sensory deficits, its a good thing. You'll have to locate the source of the irritation. maybe its your wallet that you sit on, maybe it's your reaction to BA in the last injection....many many possibilities. Regular adjustments from your chiropractor will get you back on your feet much faster than without.
If you DO have a sensory deficit, your best bet unfortunately, is to get an MRI done. It's expensive, but it will save you a lot of $$$ doing it and finding out the cause of your problem, rather than spending more money trying to treat an unknown cause.....get what im saying?
ask me if you have any questions.
