What Causes Electric Shock Feeling In Knee Cap While Having Osteoarthritis?

I was on my normal 5 mile walk yesterday and all of a sudden going up a hill I got this sudden sharp pain that ran thought my knee cap. Almost like an electrical shock. Only lasted a few seconds but started walking and it happened again. Got home did the whole ice, elevate and did some stretching. Doesn t bother me to kneel or go up stairs. Today I ve has a few (3) episodes. It s totally random. I do have osteo arthritis. Any thoughts?

Hi I did review your concern.
Your electric shock like sensation over knee could be due to nerve root irritation in the back like lumbar spinal stenosis and typically occurs when you extend you back or walk on toes. I would advice you to consult a orthopaedic surgeon who can help you with diagnosis or a neurologist who can also run tests like Nerve conduction tests.
A spinal MRI after detailed neurological test would be highly advantageous here.
I hope this helps.
Let me know if you have any more questions or concerns.
Wish you healthy and happy life ahead.
