Hello all, I'm 36yo male and have persistent pain behind my right knee after first acupuncture session. I have small central disc hernia in L5/S1 and it causes some tingling sensations on my both feets. I visited on [PT performing acupuncture] qualified acupuncturist first time in my life to get help to tingling feeling on my feet. He inserted needles on my back, buttocks, tighs and calves. When he put one needle behind my right knee, I felt mediocre pain from it. I informed acupuncturist immediately about this and he said it's normal. Session ended and I left home. I've had burning intense pain on back of my right knee for 1,5 weeks now! I can't sit or drive because it intensifies the pain. I called him and he not have a clue. Doctor did Ultrasound and ENMG and both came out ok. Do I have this pain for rest of my days? What has happened?
