Hi Lynne, my joint pain was unbearable, found it hard to dress myself turn over in bed walk down the stairs etc, my onc and his team ignored it really, my sisterinlaw came to vist me and couldn't believe the state I was in I was crying with the pain! She rang the GP and I had a conference call with her, she put me on Gaberpentin and I have to say the pain inproved, it never went away but at least I was able to cope.
my Herceptin was stopped in January I had 11 of them and I have to say each day got better, I am still on Gaberpentin but just take one a day instead of two, but if I forget to take that one tablet the pain is back! I also take diclofenac as and when needed but a least one a day, I feel for you, but I think you will find its nerve pain that you have and not joint pain! Your symptoms sound just like mine, ask your GP about peripheral nuropathy!
