Hello all. I am a 22 year old male, I would say about 5 months ago I started developing a stiffness in my right knee. At first it would come and then go for long periods of time. Now however it is quite frequent. I rarely feel pain in my knee, rather it feels weak, like it will give out on me when I put weight on it. It is most uncomfortable when I climb stairs. I fear it could be a running injury, as I picked up running around the same time, however I stopped running like 2 months ago and I figured it would have healed by now if it was related. Another very odd thing is during my work week (I work 12 hour shifts in manual labor where I am on my feet) my knee will not bother me. It bothers me on my off days when I am not doing as much physical stuff. Please I hope someone can help, I don't have insurance and can't really afford the doctor right now. Thanks!
