I'm with you! Got my second moderna yesterday and my arm is really sore today. Especially if I'm in air conditioning. Feels like it did when I had a frozen shoulder and lost strength in my hand and arm. Preparing myself to go on a biologic for the Crohn's disease.arm was really sore yesterday after 2nd Moderna on Tues. OK today--just usual rusty joints!
