I recently had an anaesthetic, removal of 25ml of water from the knee, an injection of cortisone, followed by PRP. Done with one catheter.

I thought cortisone might be contradictory to PRP (Platelet-Rich-Plasma) as I understand that begins by creating its own inflammation whereas cortisone is anti-inflammatory. Could you kindly let me know as I have excruciating pain since those injections. Many thanks for your help.
