Could you be allergic to this drug combo? Burning sensation in hands and feet might be an indication. You should be clear with your team about everything you are experiencing and leave them to decide whether it is appropriate to continue. According to a cousin who is a cancer nurse this combo probably has the highest rate side effects/serious allergic reactions. I have heard of Cisplatin being used as an alternative. Each drug has its own unique issues, eg, cisplatin creates more nausea and may affect hearing. Each case and situation is different. Key to success is being able to tolerate and complete your treatment cycle. Perhaps worth a proper discussion with your team.
Try and pace yourself mentally with whatever tools you have to get through the process. Let go of the anxiety if you can and focus on your life post treatment. It’s by no means easy. If you have supports that can keep you in a positive mindset you are halfway there—I wish you the very best. Do not hesitate to reach out for help and support.
