started Cymbalta (20mg 2x a day) 3 wks ago, pain has reduced a little, my frfog is better, I developed an itchy rash & still have problems sleeping. I go back to the dr tom not sure what will happen. the reduction in pain has allowed me to a least walk and exercise a little. I use willow bark lotion to deaden the pain dr said take Aleve but my stomach can't handle it. Any advice is much appreciated.
