Dr Togut uses Marcaine, due to the longevity of the the medication, like I said with the trigger point injections is to respect the releif that you get, you will feel as though you are back to your old self and over doing it in the beginning will cause you to hurt more when the Marcaine wears off , though if you give the nerves and muscles a chance to relax after being injected and start doing stuff at a slow pace you may get up to several weeks of limited pain ! Like somebody here stated that each and everyone is different and it may or may not work. I also think it goes by the skill of the doctor administering the medication !
