I feel badly for you! However,.. do not give up on the Fentanyl patch. It won't hurt to give it a try, and you may be surprised and finally recieve some much needed relief.
I just started the Fentanyl patch a couple of months ago, and I still need an adjustment on it....either to a higher dose or changed out every 48hrs. We have several members on this and have heard good reports on it here.
I understand totally how you feel, as I too have been chasing the correct dosage for quite some time ...of any med. My PCd is cautious...but that is not really a bad thing as long as he continues to make adjustments in the right direction. It takes time, especially when you have to wait 30 days for the next appointemnt. So in essence it can take several months to get there....at least with my PCD.
I don't know if you have met Straydog (Moderator) ..yet, but she may be a good one to visit with the leg swelling problem. I think Stingray...has this problem as well..and maybe he will pop in to visit with you as well.
Good luck, and I do hope you reconsider the Patch.
