Hi Lizfuller,
I'm so sorry that you are having such problems! My husband had lung cancer. He also was taking Keytruda treatments and it nearly killed him! He got pancreatitis which is a known side effect of Keytruda. He lost weight and was down to 120 lbs! He felt dizzy, ill, had more shortness of breath. Luckily, our primary care doctor, not the cancer doctor, got my husband to the correct specialist. My husband started to improve and get better but he refused to ever get another Keytruda treatment. This made our cancer doctor unhappy since our insurance had just approved another 6 months of Keytruda. The Keytruda treatments cost $25,000 per infusion at that time. They are probably more expensive now. My husband lived 13 years with lung cancer. He died two months ago. However, I'm sure that if he had continued on with the Keytruda he would have died a lot sooner. You might want to look up the side effects of Keytruda on the Mayo Clinic website and also the side effects of any other medications you take.
I wish you the best and will say a prayer for you.
