Hi Hope this message finds you in good health. I have gone through your complaints and understand your concern. well,if u have no symptoms as such as of now,u should not be much worried. its only when the nerve is compressen then u might get that radiating pain. u can well continue with the job but with a few precautions- 1. do not lift heavy weights, 2. avoid doing strenous things while bending down. 3. long time standing should be avoided.as far as possible,try sitting for atleast 5 min at hourly intervals 4. use lumboscaral belt while on job,so that u do not injure the disc and facetal joints anymore further. if u follow these instructions,i dont see any reason,why u should stop the job..Nothing to worry about. I hope your question has been answered. If you have any follow-up queries,feel free to consult me anytime. Thanks,Take care,God bless.
