I am 21 year old female that is over weight. Lately I have been getting goosebumps for no reason yesterday I counted 11 different occasions when they occurred today i lost count after 15. I am not cold and i am not doing anything scary. Also, I have a rash on my stomach I did some research and I think that it maybe Pityriasis rosea . It itches sometimes but not always. It has spread to my back and a little on my upper shoulder near my armpit. I quit smoking 2 weeks ago today but i cant remember if i had the rash before then or not. I just got over a really bad cold last week but I took the medicine that I normally take when I am sick. Also, my doctor just put me on Adderal 10 mg twice a day and I am also on Lexapro 20mg. I don t know what is going on with my body! I am under a great deal of stress with school, internship, my father dying last month and money in general.
