intense itching, NOT on belly?!

ive read its normal to have an itchy belly, boobs, or butt because of growing tissue. if its intense, it could be PUPPS. BUT, im itching almost only on my hands and feet?! so much it wakes me up in my sleep because they burn or sting from scratching in my sleep.. im about 28 weeks along. ive read this vould be cholestasis? any mamas have any experience with this?! im going to ask at my appointment today, but i need some comfort!!!
