Basically, I'm wondering about it because my fraternal twin sister has had one of them. Her first one was during when our mom was recovering from brain tumor removal surgery. She has of yet not gotten her routine blood work for it. Because again she has a lot her on plate. Between her work, caring for both our father, me since our mom's death (6 mos ago). At the same time she is also battling yet another cold. In which she gets from time to time. She insists thats shes fine, needs to take over counter medicine, cough drops, tea. While doing everything else. She has finally gotten her own theraphy, spl (spelling) started, but still feel shes need more than that.
