I am so sorry to hear that you are going through this right now - I really hope that the RSD isn't spreading.

I would deffinately recommend that you go and see a PM dr (if you have one) to see if he/she suspects that the RSD is spreading. You could also try and do some gentle excersises on your arm, to see if they help - thats what I did when my RSD started to spread.

I have never tried the Grape Seed Extract, but I have heard of some people who say that it can help with the swelling etc. You can take GSE with medications as it is an herbal tablet, so it shouldn't cause you any problems - but I would speak to your dr before you try it, if you decide to, just to be on the safe side!!

Please keep us all updated when you can
Love and best wishes
Alison
