ummm, no. Don't go to a chiro. Go to a doctor and have it x-rayed first and make sure you didn't herniate a disk( you can do this a numerous amount of ways), which is almost always the cause for sciatic pain. You may need an MRI to better determine the condition of your back(spondylolisis, acute pars fractures, etc), if it is any of these things, having a chiro crack your back could really fuck you up. I have a bad disk myself, and after almost 5 years, I've learned to live with it. sciatic pain is a real bitch though.
Go to the doctor, X-ray, MRI and find the root cause of the problem before doing anything to your back. I hope you have good health insurance. MRI goes for 1200 smackers.
