I’m 78 year old male and had my left kidney removed with renal cell carcinoma on 9/24/2025. Today is 11/11/2025. I had my first Keytruda infusion on 11/7/2025, 400 mg.
Within 5 -7 hours I had severe muscle pan in both hands, arms and shoulders. I could not lift a water bottle with both hands for example.
I do have arthritis.
I took 40 mg prednisone that night and by morning I was so much better.
My oncologist doesn’t know what to do relative to Gavin the second infusion in 6 weeks. Trying to work with my rheumatologist to come up with a solution if I have a second infusion or whether the benefit of Keytruda is worth the pain.
What’s very frustrating to me is that there is no clear answer or direction. Don’t know what to do, if anything, at this point.
