Hi All. here after SCT 3+_ years ago and in remission for that time. Oncologist wanted to perform a Base Line PET Scan and I popped positive for lesion in collar bone. Received 1st treatment of Darzalex FastPro/Revlimid/and Dexamethasone. 2nd day after treatment came down with pretty severe pain in the collarbone area. Has anyone received this treatment regimen and experienced moderate to severe pain? I'm thinking there is a battle going on between the lesion site and the chemo drugs causing the pain? Such a thing? Pain under control but 1st day was NOT fun. Thanks all! Mike Bruce
