Hi sarah2254,
I see you've not had a response, so I'll say something. Most people find slowly increasing activity to be a very good path. This was the route I took with my feet. I took months getting back to "normal" and that felt very doable and correct for me. This wasn't RSI, but ultimately it is all the same condition. Mine was just pain in the bottom of the foot.
I don't know if you're aware of this, but Forest, who started this site suffered from RSI, recovered with Dr. Sarno's work, and was inspired to help others. So you're in very good company in your path to recovery! Many have come here over the years with RSI and recovered. Take confidence, read success stories, and do one of the programs if you're not already.
Andy
