My 19 yr oldold daughter donated plasma for the second time, ever, today. The first was two days ago. She said after each time, when the blood was returned to her, she had very uncomfortable symtomssymtoms of having a cold feeling, shortness of breath and chest hurting. These feelings last the entire time the blood is being returned to her body. Today, however, she has felt very sick to her stomach since donating. She followed all directions and ate and drank before and after. Not sure what s going on.
