Thank you Deanna! Cortisone always works about a week for me also!! I'm getting ready for another morphine injection on Tuesday. I'm so nervous- it's very painful due to the large amount of fluid injected- the marcaine then the morphine mixed with saline. I will be partially sedated with Actiq (fentanyl citrate oralet). I hope it will again help me for about a month. Arthritis- what a challenge! Margaret
