For me it is Hydrocodone ( Vicodin ) 5-325 I take 1 or 2 a day depending what I did in the day.For me it helps the pain go down..when it is rising...because if I let the pain continue after doing too much no meds work for me..If I am at home and did not have to get much done..I rest like I am suppose to and use my electric blanket when I feel the pain rising..that helps a lot..but I am not always at home when the pain starts rising..so I will take a vicodin to stop it from rising until I can get home..
