I can second dabbos comment on Bio Freeze. You can purchase it on e-bay http://search.ebay.com/biofreeze_W0Q...tsearchZSearch And on Amazon http://www.amazon.com/s/ref=nb_ss_gw...o.x=12&Go.y=14 also Icy Hot patches can help sometimes you can purchase those in the local drug store.
Try to put some hot packs on your flared areas... Just be cautious not too burn your self. You can purchase some really nice reusable hot packs in the drug store or place some rice in a sock and tie it off. Then heat it in a microwave just be cautious as it can heat quickly and become very hot... So check it and use it as it is comfortable.
If you can research for a pain management doctor that would be a good start especially if there has been a mention of RSD as you will need special considerations prior to surgery such as a block etc to help keep the RSD from spreading...
Best of luck...
Many Hugs
