She further said that she went to the bathroom a lot and needed help to walk to the bathroom. She had become dehydrated because it was hard to drink due to the nausea. It was also hard to breathe for her but she did convey that as she had pre-existing sinus problems, so she indicated that she often had trouble breathing. The symptoms lasted for 3 to 4 days. She stated that she almost went to the hospital because her symptoms were so awful/debilitating. She started to feel "human" again by the weekend, on Saturday and had not seen her physician but she did call him and he had advised her not to get the second shot of the Shingrix series.
