"Jolts" to knee?


Shortly after my injury about 17 years ago I experienced numbness/pain in my left foot and toes. It feels like it is in the bone and travels around some. They checked me for sciatica then but the tests were negative.

Now just in the last month I have had several jolts to my right knee, right in the center, just above the kneecap. It feels sorta like an electrical shock, very severe and sudden, does not appear to be in the joint. Twice it actually was so bad that I just let myself fall down to the ground , another time was the same but I just put all my weight leaning on a walking stick which sunk 6" into the ground.

When it happens I have never been doing anything unusual, just walking, no twisting or jumping . It just comes from nowhere and in a couple seconds there is no more pain or stiffness or anything.

Does this sound like sciatica? Or any other ideas what it could be??



  • Have you had an injury to the knee? I had x-rays and ultrasounds done to my knees and then got steroid injection to each knee and iced every few hours after. The x-rays will show if any Osteoarthritis and ultrasounds will show any peribursitis or bursitis. my knee has given out on me before also and I have sciatica also but they say it's not from lower back anymore but I don't know. Get your knee checked out and see if it's something there first since you've had tests already for sciatica. Just sharing my experience. Charry

  • No injuries to my knee that I am aware of. I do kneel on pillows when I am on the computer, so I don't stay on too long, been doing that for years because I can't sit.

    99.9% of the time my knee is fine, no pain or soreness. and then, BAM, I'm on the ground. It does not feel like arthritis or bursititis.
