Thank you all so much for your responses!
I have been diagnosed with Scheurmmans and when the numbness started in my left leg, my PM Doc immediately got me into hospital for an MRI scan. The MRI scan didn't show any spinal changes but I was told that it could be either the Scheurmann's or the RSD causing it. My PM Doc hasn't seen numbness in any other RSD patient so isn't sure if it's that and if it is, what to do about it!
The numbness in my hand is getting worse and I now have tingling in my fingers and pins and needles. My mums getting really worried about it so called my PM Doctors Nurse who told her she would speak to the Neurologist and get back asap ... still no word after 4 days though!
I just want to know whats causing it. I'm sick of not being able to carry foods, hold drinks, cut things up etc

!
Thanks so much again and I will be sure to keep you all updated!
