Electric-shock like pain in knee

Hello; for the past few months I have been experiencing a pain in my
knee, it is just to the outside of the patella. It is a very sharp pain, like an electrical shock. It happens totally at random. It can happen when I am walking, sitting, sleeping, etc. When the pain is not occurring, my knee feels
completely normal. When it happens, it usually happens every few
seconds or minutes, then stops for several hours. I am not aware of
any injury or unusual stress to that area. X-ray was normal and doctor's examination was clear. Any ideas?

I have suffered on & off for years with this. X ray & examination showed nothing. I am fit & healthy normally. It can be gone for years & then come back & stay for months. The pain is very sharp & brief & then goes without leaving any pain behind. It makes my eyes water the pain is so sharp. No rhyme or reason for the attacks..................
Anyone, any Ideas!!!!!
i have it too!  5 times in past 10 days. Excruciating, unbearable for about 5 seconds then -poof- gone with no residual pain

I have a pain like this on the backside of my knee.  It started random, but now seems to occur more when I bend my toes up towards my knee.  I have tried to find info on this and sciatica seems to fit the bill more than anything, but everyone says that starts in the thigh and I don't have pain in my thigh.  It is quick, severe, and feels like someone is shocking me. I would guess that a shocking pain would be associated with a nerve being pinched.  Let me know if you find out anything else.

I am with you.  This happened to me this week for the first time ever.  It is crazy pain and a very bizarre sensation...like getting electric shock .  It is happening to me too while I am doing very different things.

Anyone who has ideas and might give suggestions would be very appreciated.

This is so strange..  I am experiencing this also.  It feels like electric shocks... in my knee cap...  and it lasts about 2 minutes... all tiny shocks.. (painfull).  I wonder if this has anything to do with diabetes since I suffer from that as well.. anyone else?

I too have been feeling electric shocks in my left knee.  It may have to do with the hernias I have in my spinal cord that off and on press the nerve and thus cause the shock.  Is this is a possibility?

Hi, my name is Marco from Rome Italy.
I've been suffering from the same electric shock at my left knee, close to the patella on the left side of it. It started about 20 days ago (end of Aug 2008).
I guess it's a weird kind of neuropathy.
Anyway i played soccer until almost 3 yrs ago and in november 2005 i suffered an achillis' tendon break at the same leg (left leg).
Since then i put on about 10 kgs of weight. Is all of these things related?
Dunno if i suffer from diabetis.

I also have "THE SHOCK" behind my right knee. I have been suffering from it for about 2 mts now.I wondered if the Dr would think I'm crazy, I had put off going... How do you explain to some one this CRAZY feeling? Sure enough, she had no answers. I am sched for a MRI on friday to ck my central nervous system, if that shows nothing they will do  more testing. Hopefully I will have some answers for you guys. I am so ready to find out something.... My happens at any time, I cant even cross my rt leg and it is very scary when I am driving... I cant do anything but let it pass and use my left leg to break...
I am 36 and healthy. Let you know something soon.

I have been having this same problem for 6 months, I will be sitting and all of a sudden, this sharp pinching pain hits my in my knee, one or the other, sometimes in both knees at the same time, I will itch/rub untill it goes away in a few seconds. But it takes my breath out and I jerk in response to the shock. I have been a Diabetic for 13 years and no doctor has been able to explian this. Does anyone here even know what it is called? Or what causes it?

I also have been suffering from the same knee pain. I have just read all the entries from July 2007, until the last one 2 days ago, on Oct. 08 and have yet to see anyone mention a solution.  Has anyone found something to help with this crazy  pain?

Dear All,
The closest thing I can come up with from my on line research is
"Piriformis Syndrome".  Check out the following link for more information:

Hope this helps someone find some answers.
