This has happened 4 times in the last few years where I get a sudden sharp pain in my knee (always the same one) that hurts enough that I have to stop what I'm doing, but then completely disappears after about 10-15 minutes.
Along with the pain is a feeling that something is out of place or not right in my knee cap. It's like something has clicked out of place bit then goes back and then the pain disappears.
No swelling, bruising or injury. No need to rest it, once the pain has gone I'm good to go and the pain doesn't come back.
It's so odd, I'm wondering if anyone has experienced this and knows what it is?
