To answer your question yes it is possible that even if the knee doesnít get inflamed, you can get that kind of pain. Do see a doctor to have it checked for possible arthritis, etc. Also ask for pain medication because from the way you described it, that really hurts a lot. For joint pains, ask your doctor about tramadol. I take it for my rheumatoid arthritis and it really helps. Just update us on what your doctor will tell you. Take care.
