Tracy has it right. What side effects caused by which drugs/treatments? And every person reacts differently to every drug/treatment. A WhatNexter who had the same diagnosis and treatment as I had totally different side effects. We got together and discussed all our issues and found it so interesting how differently our bodies reacted to the same exact treatment. So it will be different for every person.
Some of my side effects resolved immediately while others have lingered and I am approaching my 2-year anniversary of my last treatment. As Tracy said, one can psychological as well as physical problems. I never had lingering psychological issues, but my physical issues will probably never resolve completely.
Just stay on top of them and talk to your doctors about them. I have had several health issues over the past few years that have taken many months to diagnose...all either directly or indirectly due to the chemo. I recently had GYN problems which my oncologist at first didn't think were due to the chemo, but my GYN said he has seen many times in women who've received chemo. So he decided to be a bit more proactive in doing tests rather than taking a "wait and see" approach.
Although I do get frustrated, it's the new me and so I'm a bit more beat up than I ever thought I'd be at this age. But I'm here and I'm cancer-free.
