Hi. I'm so sorry to hear about your pain ((hugs)) - I hope you are feeling better now. I have had RSD since I was 12 years old (i'm now 13) so I know how hard it is dealing with RSD at such a young age when all you want to do is go out with your friends and have fun. If you ever want to chat I am here for you.
Why won't the hospital give you any pain meds? I think it is discusting that you are ment to suffer in so much pain without any pain relief at all.
It may be helpful for you to keep a diary or a journal about your RSD so that you can show it to the doctors and then hopefully they will realise that you need some help.
Please keep us all updated
Love and best wishes
Alison
