I had another reaction to the chemo yesterday. They still think it is an "infusion" reaction rather than an allergic reaction, and that I have a sensitivity to the base of the medicine. Only one of these treatments remain (in three weeks), and the oncologist and pharmacist are still deciding on the best way to prevent another reaction. This drug is the best for my kind of cancer, so they are doing everything they can to make sure I can still use it.
I also suspect that the difficulty I've had breathing and the pain in my chest are a lingering reaction to this drug. It feels very similar to the reaction I had at the hospital, just not nearly as intense.
