I don't know what to do for the second week, my son hasn't slept prope…

I don't know what to do for the second week, my son hasn't slept properly at night for two weeks now. If he does sleep, it's only on my hands and I have to rock him while sitting on a yoga ball. His gums are swollen where his lower teeth are located, but they aren't coming in. When he cries, Kamistad gel helps temporarily, but only that. My husband tries to help, but the baby doesn't go to him at all at night, he's hysterical and crying, only to me on my arms he needs. I can barely get any sleep at night, about 2-3 hours ?
