Chemo and Guillain Barre Syndrome and r there any groups on Sunshine Coast, Coolum to Noosa Region?

Hi everyone, hope your weekends are peaceful and relaxing. I have been lucky enough to watch some whales with calves migrating south!  As I mentioned recently I had a mastectomy and a week later had a further 15 lymph nodes removed as one of two taken with the breast had a medium level of cancer.  Consequently I have a lot of nerve damage to my left arm.  I was prescribed Lyrica which gave me suicidal thoughts so have been changed to Amitriptyline which gives me some nausea and heart palpitations.  Has anyone had any experience with nerve pain and/or these drugs.  How long will the nerve pain last? Is it better to put up with it rather than take medication for it?  I would normally ask my surgeon but she has just gone on holidays.  Thanks, Pauline
