H.,
It sounds like she's in pain at night, with crying and screaming and such. You've tried great strategies- good for you for sticking it out with her. Crying is her way of telling you something's not right, so crying it out tells her that you're not willing to help her out. And reading- although a great thing to do- at night reinforces being awake. So...have you tried orajel and tylenol at night? It sounds like her teeth are giving her a heck of a time. Or her ears- has she had her followup to be sure it's all cleared up? Another thought- have you introduced a new food recently? Like over the holidays? There may be something upsetting her tummy if you've begun new foods. OR- if you're nursing, are YOU eating something new? If you can't figure it out, a trip to the doc may be in order, since it really sounds like she's in pain. So much luck to you, and keep sticking with her in this difficult time for all of you!
