Hi Miffy,
I started out on Degarelix and I got a lot of pain with that. I had quite a severe reaction in general, but I could not convince my onco to change it.
After the Degarelix stopped working, I had started chemo (Docetaxel) and I found the two medications together amplified the side effects and so I insisted that I stop the Degarelix. The onco then changed my HT to Decapeptyl (that was in November 17) and I have been on that since. I have had no side effects at all with Decapeptyl.
So a bit of a long winded reply to say that I have not had the pain that your dad has had.
I was just going to add that I believe that HT does in itself cause some pain, but I notice that while I have been writing this (interrupted by a phone call from my son) Lyn has responded with exactly that answer.
Best wishes,
Peter
