Hi I am sorry about your daughters pain. I have RSD and did not have an injury. I thought I did but went to the orthopedic right away and there was no injury so when my pain continued to increase I was sent to the neurologist who preformed many tests emg/nc,mris etc. I also went to other specialties like endocronoligst,rheumatologists,many pain doc,another neuro I could go on. I first was dx with peripheral neuropathy and then rsd. My condition is in my legs but then 6 months after that began I developed severe eye pain and sometimes get severe head aches from the eye pain which we are thinking is now rsd since every other condition that would cause this pain has been ruled out. I developed PN at 28 and though I was older then your d it is still young. What dx tests has your daughter had?What kind of blood work has she had testing for auto immune conditions or other vitamin deficiencies? Has she been sick in the past with anything? Any other problems she has had such as a fall in the past or health problems? I am sorry I don't have more answers for you. If all the testing has been done and the pain treatment is not working I suggest she see's a pain doctor/anestesolgist. My neuro does do some with pain meds and treatment but overall the pain doctor works more with that.
