my next infusion is coming up in January, I spoke to the nurse after I had posted my comment on MCC and coincidentally she just had a patient visit who reported the same symptom, she suggested physical therapy, the IVs were given in the same arm, left, I'm right handed and wanted to keep use of the right arm in case there is a mishap with the left arm, both shoulders and upper arms are effected by now, the left one with stronger symptoms, discomfort and can't fully lift it without pain- also strange that after the 2nd infusion I started feeling pain on and off where I was given the last 2 covid vaccines, 6 months apart, here in each arm, I will report back after the infusion-
