New lesion
6 month MRI showed a new right lateral lesion C4/C5.....
After reading the possible symptoms of a lesion here, it's all exactly what I've been telling the ms team for months ....intense pain in lower neck and unable to move my right arm or leg as I want to.....cannot lift my right arm above the shoulder without severe burning pain.....
Yippee .....still I keep trying

Sounds like the lesion may have manifested around the same time as you started Kesimpta when it hadn't had a chance to start fully working. Unlucky but the drug should perform better from now so hopefully no more from now onwards.
I hope the results help your MS team to more effectively help you!
