Hi bc,
Welcome to the group. I'm not sure if what I have to say will be helpful or not. As for the joint pains, I remember well when Mike as on Carboplatin and taxol he would always start to feel bad about the 3rd or 4th day after treatments and he experienced quite a bit of achiness and joint pain. I believe the onc said the carboplatin was responsible for this. As for the chest pain, he didn't have that. The only other carboplatin side effect he had was hair loss. I don't know if this is helpful or not. Others will be along soon and perhaps give their own experiences. This group is great for sharing . My best to you.
Sue
