My best advice would be to call your doctor and let him know immediately, JUST in case. Since you have a history with it it's better to let him check you and see.
Also, when I had it, it was primarily on my hands and feet and would get worse at night... in hindsight, i think i had it for about 2 month but reduced it to stress... i remember having had changed body washes thinking my skin was just getting sensitive.... Luckily I went in in time. I think you should get your levels checked so you know how your liver is working!!
