I am 21 years male. I have tingling nd burning sensation on my left knee. I can feel it when I seat and lye. But it little disappears when I walk. I had a left lower abdominal surgery before 6 month. Why this is happening? Sugest me remedy for this. Again I have gone through inguinal region usg. The usg report shows that a non compressible hypoechoic structure on left spermatic cord suggested thrombossed pampiniform plexus. please advice me for the knee pain.
