If you decide you must go through with it, then make sure you have a plan to deal with the aftermath caused. My primary thought I should refuse last time I was told I had to have ANOTHER nerve test. And while I knew he was right, WC could have used it as an excuse to deny benefits, so I went ahead. It is not a pleasant test without RSD, it feels like torture with... The technician abbreviated my testing because she couldn't stomach my reaction, lol. I applied Lidoderm patches immediately afterwords. I was prepared to go to the ER if need be, and my primary had agreed to fight for a SGB if need be. Although, the procedure caused a flare, luckily I was able to manage it at home.

You will need to have someone drive you home afterwards, if you choose to go through with it. Also, if they plan to test both arms, have them test your non RSD effected arm first.
