After being sick two weeks ago, I decided to return to Primal. I have been doing fairly well at staying around 100g carbs and am starting to reap the benefits of eating better.

However, today after work my right mandibular lymph node became swollen. It hasn't gone down and tingles. Has anyone else experienced this? I should mention that back when I used to get sinus infections they would swell, but this is the first time it's happened when I feel perfectly fine.
