I have used Lidocaine Infusion therapy over the years, with limited results. The theory is that Lidocaine is a nerve membrane stablizer that potentially helps people with various neuropathic (nerve) pain syndromes. What is does is calms down the nerve membrane and prevents it from firing and producing painful signals. In my experience, the infusion works for a short period of time, but once your body metabolizes the drug the effect goes away. In a very small group of folks, the relief may be longer term. There is not much downside to trying it. It is given over about 30 mins to 1 hour and will make you feel light-headed, dizzy and can lower your blood pressure. Hope this helps
