I am doing some research on the best treatment for CRPS' patients; As of now, there are a few studies made by Doctors telling patients what's best. However there isn't a single study which asks for what patients prefer. Thus can you check what type of meds you prefer in day-to-day use, in order to manage your pain. You can check as many as you want, and if there isn't your medication, contact me and I'll add it Thank you and have a low pain day
