How long does a torn knee ligament last?

When i was at work my knee went in and i fell. Ever since that happen i have been having pain in me knee. I have no medical insurance to go to the doctor and since its been almost a year i dont think my job would pay for it since i didnt finish the physical therapy. Now i have the same pain in my other knee and dont know what to do because sometimes the pain is unbearable. How long does a torn ligament last and is that what i really have wrong with my knee

The pain will continue for the rest of your life unless you get surgery on it. You probably have scar tissue in your knee which will only get worse with time.

You can tear your acl (which is the commonly torn ligament) and there wouldn't necessarily be much pain long term. Unbearable pain is probably something else. You need an x-ray or mri to get it diagnosed.
