Poor baby! (And poor mommy!) "Normal" for pain is a pretty wide range. My son was cranky when he cut his teeth. My daughter had a rotten time of it, and everyone within a 2 mile radius knew it. She cut her teeth two at a time, and wailed like a siren for days with each one.
As for what helps to soothe them - I'll second what another mom said - frozen washcloths really seemed to help. Ibuprofen helped some. Nursing helped a lot, although I began to feel like a giant walking pacifier.
I have some friends whose children were helped a lot by Hyland teething tabs (homeopathic, available widely, even at Walmart). These little tablets dissolve quickly under the tongue, and are supposed to be miraculous in helping little teethers sleep. Unfortunately, a very few children, including my dear daughter, are allergic to them. If your son is, you'll know immediately, because within two minutes of taking them he'll throw up. (No lasting effects, though.) Still, so many moms I know swear by them, if I were you I'd give it a go.
It's good that none of us remember when we cut our first teeth, isn't it? Hang in there, mom - this too shall pass.
