I work with a orthopaedic surgeon and we see many patients for knee problems, its possible you may have a lateral meniscal tear that could be compressing on a nerve you may need to have a MRI to see whats going on in there. remember x-rays only show bone! MRI shows ligaments,tendons and will show if you have a tear of any sort. Are you pregnant sometimes they wont do these trst if you are expecting but get it checked out so it dont get worse..Good luck and i hope it gets better soon..
Could be a torn meniscus. Dh had this on both knees and had surgery for it. See a dr to be sure.
I too would see your Dr. I don't know a thing about knees, but I hate to see you in pain. Good luck to you.
I do not know what this could be. Are u prego, I have heard that sometimes the baby could be sittin on a nerve or something but I dont know that he/she could be sitting on one that would affect a nerve n your knee. I would check with my dr and make sure everything is ok especially if you are prego. But this doesn't sound good especially with your knee being numb I wouldn't play/let it go too long untreated. Wish u the best!
