I'm wondering if anyone on Krytruda may have experienced GI side effects? I was diagnosed in June 2019 with melanoma stage 2B and had a successful surgery in Spetember 2019. I started a clinical trial for Keytruda on Nov 5 2019 and had my last treatment end of September 2020. I've definitely had a number of side effects but this recent bout of GI problems have not yet been assigned as a side effect. Has anyone else had this issue? I've been on pregabalin and Naproxen for Peripheral neuropathy and Osteoarthritis since May and I am curious if this recent GI issue is related.
