Hi, my mother is taking HTN meds. Recently she has been complaining of dizziness, pounding around neck and head, darkness when she lies down. this has been going on for a week. few days ago when she lied down, she complained of dizziness and as i gave my hand to help her stand up she fell down on the floor and hit her head. however, her symptoms dint worsen or disappear. i have no idea what to do or what it is?
