Have you been wearing the helmet routinely over time or is it an older helmet that you decided to wear with the new bike? I had a helmet once that would rest right on a spot in the middle of my forehead and would give me a headache if I wore it more than an hour or so. Sometimes it would be good but other times it would be uncomfortable. Have you changed your hair style? My head has about as much hair as a peach these days so I don't have many issues as long as the helmet fits initially. If the helmet has removable inserts for cleaning, you might try pulling everything out and cleaning it up and then putting it back together and see if you can smooth out some of those pressure points.
