How are you dealing with stage 4 kidney cancer treatment side effects?

Hi I am a 64 year old woman. I had my right kidney removed October 2018. I had a yearly scan until May of 2023. Found tumors in my left kidney, both lungs and lymph nodes. A biopsy showed it was kidney cancer in my lungs and lymph nodes. I was diagnosed with Stage 4 RCC and Started on Keytruda in June of 2023 by August I had side effects rashes on my feet arms and hands. The rashes than turned into bleeding ulcers. Dermatologist tried Dupixent and than Otezla both failed and had their own side effects. Than a I was prednisone high doses 80 mg for 6 months and finally relief. In February of 2024 I was put on Cabometyx. Tolerating the side effects but now I have protein in my urine another side effect of Cabo and high blood pressure.
