No, there is no way to contract CRPS from someone else. However, as they say "birds of a feather fly together" and patients or their support structures some how find each other fairly easily. The contraction of CRPS has been identified as a triggering event causing a neurological reaction. However, one doctor (Dr. Pradeep Chopra, MD, MHCM in Rhode Island, US) observed that many patients in fact mention having two injuries in a short period of time around the initial event, suggesting the second injury was in fact the triggering event, not the initial.
