Therapeutic measures were taken as a result of pulmonary embolism. Clinical courses: Caller stated that she had a terrible reaction to the covid vaccine (Not confirmed if the Pfizer brand) where she received 3 shots. The patient  got violently ill when she had her third Pfizer COVID vaccine. She had pulmonary embolism, falling hair and got really sick when she got her third Pfizer COVID vaccine. Confirms all of her COVID-19 Vaccines were manufactured by Pfizer. She had 3 doses and is not getting any more. She was violently ill and sick for 10 days with the last COVID-19 Vaccine shot. It was right after got the third shot, the day after. States she got the third shot on a Thursday. She was throwing up, had a fever, had a headache, diarrhea, it was awful. States she probably would have rather had COVID than got the shot. She had long hair. She would play with her hair, it didn't come out in chunks, but more and more was coming out in the tub and towel. Wanted to know what was causing this. Can't say for sure that losing her hair and the pulmonary embolism was from the COVID shots, but she knows they are side effects and has no other history of that. She doesn't know. Her pharmacist just told her to report it. Investigations: For the pulmonary embolism, she went to their local hospital, but they couldn't handle it so the ambulance took her to Trauma in (Withheld address). With regards to her Pulmonary Embolism, she was admitted for almost a week, it was pretty serious. If her granddaughter hadn't been there, caller wouldn't be here. Caller passed out. She had no pain or anything. She stood up, thought she had to throw up, thought she was going to pass out. She fell, fainted, and woke up enough to holler her granddaughter's name. By the time the ambulance got there, caller couldn't breathe, her oxygen level was 40. Caller was begging for oxygen. They took her to the local hospital and guesses a lady was trained at Trauma and knew their local hospital would not be able to handle her lung without doing surgery so they took caller to Trauma, which is more advanced. They were wonderful, gave her all the medicines and put her on machine that took care of it. She wanted Pfizer to be aware of the reaction she was having.
