Lamictal lymph node

Hello, I'm just really trying to make sense of things and wanna know if others have had this experience and if I could see a doctor. I have been on Lamictal for about 2 weeks now. Lamictal has been AMAZING for my bipolar especially mood swings and anxiety. Luckily for me I did not experience any side effects in the beginning. But 2 days ago I worked my way up to 50mg (2 25mg a day) and the day after I went up I woke up with a crazy neck pain I couldn't even turn my head. I thought maybe I slept on my neck the wrong way or something. Then I noticed a bump on the back of my head right above my ear and the bump hurts so much when I rub it, lymph nodes swollen, dry throat, hard to swallow etc. I didn't associate it with the medication until I did some digging and found other people stories about this, but it wasn't a lot of people because of how rare this side effect is. I really like this medication and want to continue it but l'm scared of this side effect and that it could be dangerous. Has anyone experienced something similar to this? Does it go away? I'm seeing my psychiatrist tomorrow to discuss this. Just wanted to hear others experience.
