so i'm having an OB, but there's some funny things elsewhere on my body that i'm experiencing at the same time. i'm curious to see if anybody else has had similar experiences, or if i'm just all sorts of sick.

i get splotches of red all over my skin. it's very noticeable. i look like i have polka dots, and it's everywhere. i notice it the most when i'm fresh out of the shower, but in general, i've noticed my skin gets these red dots. it's not hives, anything raised, it looks like small patches of blushing.

also, my scalp has been itching. it's not dandruff, nothing flaking. but i'll get these itchy patches, and when i scratch them, they scab. but keep itching. and i haven't had any go away yet. please don't tell my i have herpes in my hair. that might be the most ridiculous situation ever. however, i can't help but notice similarities between how my scalp itches, and how my OB downstairs itches. thoughts?
i have switched hair products or made any such changes in my routines.

and i've been bruising incredibly easily. is this just because my immune system is so down? my diet hasn't changed, so i doubt it's lack of iron.

i don't know, just curious if anyone had anything similar or any ideas.
