This morning when I woke up I noticed the back of my arm is really sore. It feels like it’s the muscle. I was totally pain free when I went to bed last night and didn’t hurt myself at all. 

Could this be a side effect of Lamictal? 
Have you experienced similar and did it go away if so? I am having SO many side effects I want off and never want to take meds ever again I always always have fucking side effects that ruin my life I’m so over it lol
