Hi, I had Docetaxel last year finished in July. Ever since I've found walking any distance hard work. Any hills or inclines especially challenging. Stairs are a bit of a chore as well. I've had loads of checks including MRI scans of my spine to make sure nothing else going on, and it isn't. So the findings are...its after effects of the chemotherapy.
Good news is that since then my PSA has been undetectable until last test when it rose to 0.4. Next blood test this week with 6 month follow up with Oncology. I've everything crossed that the PSA is still very low.
Keep at it. It's not great at the time but worth it.
