How many other people are having sore upper arms since starting Kesimpta ? Because my arms did not hurt before I started taking Kesimpta and now they’re so sore and they seem to like get so hard and tight muscles and I’m fearful of where else that can go or happen or what else It could do to my body. I started it in April and now I can’t reach behind me without it, making me wanna scream in pain. and I’m just wondering because they’re saying the muscle arm problems are MS so I’m wondering are there any other people having muscle arm issues or muscle issues in general with the Kesimpta ? I would truly like to know am I wrong is it MS or is it the Kesimpta? I’m trying to figure it out truly Am I wrong or are they wrong??
