 Doctor, you just spoke about injections, so it looks like a big, for a big problem there is a very small solution just by injections now, can you please elaborate about how spine injections work? Yeah, so yeah, as you said it is a simple solution for something which looks like a big problem and interestingly we have found very good results with spraying some steroid and some local anesthetic around the nerve which is compressed by the disk, for this you should understand one basic fact that whenever a nerve is compressed it gets inflamed, it gets swollen up, it becomes red, like we see it when we open up the spine and see the nerve it will be red in color, it will be inflamed, so a steroid is a very strong anti-inflammatory medicine, there are people who say that steroids do not work but what we have seen is that a lot of evidence is also there in support of giving a steroid around the nerve root, especially when you want to avoid surgery, so we take a long needle, we look under an image guidance where we see under an X-ray machine, a portable X-ray machine and we position the needle just next to the nerve and then we spray the steroid around the nerve and that helps the patients almost instantly, like they are able to experience the pain relief instantly and you may be thinking does this really last, you know how long or do they have to keep taking these injections again and again, most of the time they do not have to take it again, it is a one time thing and if at all required it may be given once more so that the anti-inflammatory effect of the steroid works better, so and we found long lasting relief with the steroid injections.
