thanks for the articles they were great. i have a question that i havent really asked anyone with rsd. have you noticed that since your onset of rsd that you have allergic reations to more med or anything for that fact than compared to before rsd. in my case . since having rsd the only antibiotics that i can take is levaquin vancomacyin and gentamaycin thats it. deathly allergic to morphine even tho at one point i was on kadian for 2 yrs no problems,,its like the longer i have rsd the worse that reactions get . i know that the sympathic nervose system has alot to do with just wanted to know if anyone else has this problem or like my sister says im just a freak a nature lol let me know my pm and neuro and a reasearch dr that i know are doin a study on ppl with scs and the way that the sympathic system works with rsd ie bp heart rate etc
