Ditto! My son started teething about 3 months also. He's 14 months now and still drooling and crying. I had forgotten how miserable babies are while teething. I find that a sippy cup with ice and water helps him at this age, but at 3 months there's not much you can do besides Oraljel, teething tablets (they sort of work) and love:)
Good luck to us all!
