Yes, they are amazing! Not available in Thailand, so I ordered some on ebay. My sister had chronic back pain, she had an American guest at the hotel she works at in UK who recognized her problem. He recommended naproxen sodium. The next time he saw her, he said 'The pain has disappeared from your face, too! She is astounded to this day how quickly they took effect, and she hasn't had to take any recently.
My story is also knee inflamation and swelling due to years of weight training I think. I have taken four tablets since they arrived about 5 weeks ago! I have had no pain or swelling since! I am starting to believe in miracles!
