I had a simular incident two months ago, as I injured my foot that is affected by CRPS. The best thing you can do is contrast baths to help prevent the nerves becoming to sensitive.
Contrasts baths are taking the foot and placing it in hot water for 2 minutes and then immediately submerge the foot into cold water for 2 minutes. Repeat twice for each treatment and do this daily for a couple of weeks. It helped me immensly and prevented the injury into turning into a new CRPS issue. It feels back to it's normal pain levels after two weeks of the contrast baths. Hope this helps and I'm glad you came back to the group. Keep us posted on how you are doing.
