Painful! I have had a similar experience but with a penny. It hurts!!!

One thing that I have done since I found out about the RSD & alloydonia is I constantly touch my feet. Now don't get me wrong, sometimes this hurts but it ends up feeling relieved. If I can get through the pain of my boyfriend massaging the foot very very very lightly then I call it a successful day. Closing my eyes and meditating on the pain while he does this has been a big long term success for me. It has desensitized my pain immensely. There was a time I could take showers because the water felt like daggers in the tops of my feet.

My PT was shocked that this helped me but said Continue on if it feels good in the long run. It is such a mysterious disease and what works for one person doesn't for another but I thought I would share in hopes that it could bring you the slightest bit of relief!

(PS- I have also thought about getting a size bigger tennis shoes for the days my feet just don't fit)...
