Hi, when you feel pain that is more at rest it is likely to be due to inflammation. A simple injury would give you more pain on walking. So arthritis needs to be ruled out. Have you got your knee looked at in this 1 year?
Next Steps
Get appropriate inflammatory testing done after consultation with a rheumatologist or physician.
Health Tips
Avoid overusing your knee until the problem is detected and treated so as not to cause long lasting damage
