I'm not sure if its arthritis or not. I have been having chronic knee pain for years now in both knees, I'm only 19. and I have had 2 MRI's done on my knees. But they keep showing up as "nothing serious" as my doctor would say. Now this makes no sense they say theres nothing wrong but I still lay awake at night keep up by this constant pain from my knees. The pain i experience is a constant ache, and some days its hurts to move and other times its gives me relief to move. There's a very loud crunch and pops every time I bend and most times when I step. This has become crippling, Somedays I can't even get out of bed form the pain and lack of mobility. My knees will give out all the time even sometimes when I'm not even moving and I'm just standing there. Now, I know that my mother and sister both have problems with their knees. but I'm not sure if that has much to do with it. I guess what I'm trying to ask, is if there's anyone out there that knows of a condition, or syndrome or disease that sounds similar. I'm really at my ends wit here this chronic knee pain has taken lots of my life away. and I just wanna know what is wrong with me? Thank you all so very much, for just hearing me out. I wish you the best
