Since Ketamine works on pain receptors in the brain, you will experience an immediate reduction of pain once the Ketamine infusion starts. After the infusion, you will likely feel less (if any) pain for a 24 hour period. After several consecutive treatments, many patients report a reduction/cessation of pain for days and sometimes weeks. The biggest challenge with treating CRPS is to maintain a regular infusion schedule in order to keep CRPS at bay.
