I Have A Neck Pain, And Knee Pain, That Will

I have a neck pain, and knee pain, that will not go away. I take two ibuprofen and a melatonin nightly to sleep, but the pain is present when I wake the next morning. The pain is getting worse. I believe it is most likely due to previous accidents in my youth, one motorcycle and vehicle related. Is this possible, or could it be something else entirely?
