She had COVID in Apr2020 for seven full weeks, causing a diaphragmatic hernia from coughing, has "glassing of lungs", liver and kidneys are "being watched" due to long-haul COVID. She wanted to know if her experience was normal and if her symptoms could be expected to return tonight. With the other shots it was not the same. Had four days but it was not intense. Yesterday was so intense that she thought that she might have go to the hospital. She slept for 8.5 hours and woke up not feeling as bad as last night. Pharmacist said that she may have a repeat performance. She had a headache and was not warm and not cold/shaking. Ate 1/2 bag of instant oatmeal with blueberries on it. She did not feel like that will come up. She was not hungry. It was so bad last night that she thought she was gonna die literally. It was nothing last night, was bad but not like she was going to die. This could be normal response to this version then okay. She wanted to know if she will have to take the shot take every six months. Other times that she took the shot and for four days, she was not herself. The reaction with the others as the first day was not so good as the fourth day, it started getting better. Pharmacist said it may well be that maybe in her body there was something going on and when that went in it started fighting really hard. She does not know.
