Hello. Last night while carrying groceries upnthe stairs to my apartment, I felt a frightening rush of some type, dizzying, to my head, and was suddenly slammed to the left, very hard, into the wall, hitting my shoulder very hard., I almost lost my balance and fell, but was able to hold on to the wall it felt like someone squeezed my head hard, and the stairs beneath me had jolted hard, as if UN a terrible earthquake, of course there was none. If the walk hadn't been there i would have been slammed hard to the ground. That is the frightening party it was as if someone pushed ne very hard to the left, and I would have hit the ground at a frightening speed. I worry that it could have been a stroke. I was sick to my stomach, and almost passed out. I am a very young 63 years of age, female, and still working very hard physically at my job, every day, and always take the stairs quickly. It was terrifying. Have never felt the onset of anything like this. Could it be a stroke?
