pain
"It works pretty well for me until it starts to wear off on the 5-7th day. I think there should be 5 patches given a month instead of 4 per 28 days. Or the manufacturer needs to improve the quality and lasting power of each patch. 

I do have to admit without this medication, i would be unable to have a normal life. My pain level would be about an 8 on average without it, and thank goodness I was referred to my doctor by my orthopedic surgeon. I occasionally have a little itch under the patch when it gets wet. I hate that it is not more waterproof. I believe this is part of the reason they lose their strength. I do have Norco to supplement my pain relief, but if the patches would hold their potency, i wouldn't have to use the Norco."
