@beebe I agree after what it did to me with no indication of any cance I had severe arthritis, muscle spasms lasting hours, lung nodules and then shortness of breath which turned out to be Drug-induced pneumonitis. I am now on high levels of prednisone and oxygen. Until Keytruda infusions I was able to do 180+ cardio exercises and lift weights. Now I need oxygen to go up and down stairs, lost 10 lbs. and all my muscle mass is gone. The Drug-induced pneumonitis started to show in a CT scan but they gave me a third treatment and everything went down hill. I stopped due to the arthritis and muscle spasms and then the breathing problems started 8 weeks after the last. This stuff at $130,000.00+/ treatment not for “just in case a small undetectable cancer cell is floating around.” No matter what they tell you. I wish I knew how common adverse side effects are. They told me “don’t worry the side effects are rare”. Turns out 40%+ class A side effects is the going rate.
