@Fionap2017 and @"Kiwi Angel"You have described my current experience precisely. I am four weeks past my last dose of chemo. I live on top of a hill and walk a lot in a hilly area. I am genuinely shocked how hard it is now. For me it kicked in after my third round of TC Steph, fine on the flat but insane chest bursting heart, dizziness & nausea on a incline. But this last week my quadriceps have started to become stiff and sore as well. I'm thinking it could be chemopause aches and pains. But honestly, who can tell at this point? Bloody annoying and rather unpleasant :#
