"i had a torn tendon in my knee and had to have surgery. they gave me this for my pain. it has been relatively good. it takes my pain away for about 4 hours then i need to take it again. but now i&#039;ve got to take it every 6 hours and it doesn&#039;t last that long. so for 2 hours i have to suffer. so for long lasting pain management it doesn&#039;t work that well, but for short term, it&#039;s great. and it doesn&#039;t upset my stomach."
