J.,
If you haven't received this already - go to the doc.
Usually breastfeeding soothes teething. My son still looks for comfort when he's teething. I'm thinking possible earache or something else in addition to teething - but, I am not a doctor.
I'd say there might be something else up.
We use Tylenol/Motrin per pediatrician recommendation for teething pain, but arnica montana works also.
Good luck,
M.
