Could have been a case of "Mild CRPS". In these very rare cases, CRPS can go away quickly. Usually within 4-6 weeks. The symptoms of "mild crps" are similar to "Regular Crps". The only difference is that the symptoms are not generally as severe. I would continue to work with your doctor, and maybe ask him/her if physical therapy would be beneficial. I have full blown CRPS, I took PT for 3-4 months, it can be pivotal in helping to keep mobility and help stave off severe atrophy.
You wanna know the funny truth? My daily
PT routine is comprised of things like typing my shoes, gentle house work, and silly things like that!
