I was diagnosed with MS in 2014. My symptoms can be traced back to 2007. I started on Copaxone, then Tecfidera, and am now on Tysabri. I have only 3 lesions in my brain. Lesions in my spinal column are my major problem. Fatigue, blurry vision, stiffness and spasms in my right arm/hand, back, and legs along with Trigeminal Neuralgia and numerous sensory annoyances are my major complaints. I'm a teacher and the school year is looming. I have missed a great deal of work in the past 2 school years due to 5 relapses. I'm having a great deal of anxiety over going back to work. When does a person with MS know enough is enough??
