When I lay both my legs straight out in front of me my left knee cap is healthy and strong but it seems like my right knee cap is not even there it is just flat where my other one has bone and it hurts all the time no matter what..not a horrible pain but discomfort i guess.....
Hello, I read carefully your query and understand your concern. The symptoms seem to be related to a subluxation of the patella which is the knee cap. I suggest doing a X-ray of the knee for further evaluation. Meanwhile, I suggest using anti-inflammatory medications such as Acetaminophen to relieve the pain. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
