The clinical course reported as below: She said she had the care here. She said her first shot was 22Mar2021 and 2 days later (on 24Mar2021) she had severe stomach cramps, diarrhea, very extreme nausea, she broke out in cold sweats. She said she attributed it to stress in her life, but no its not, she played it off, she had never felt like that ever, she slept it off, next day she was fine, she was tired but fine. She said the next days there was no nausea and no cramping anymore, it all hit all the sudden, her fingers felt tingly, she had nausea, diarrhea, the nausea was 3 or 4 hours, the diarrhea was 24 hours. She said she was at work, she did not have a fever, she took her temperature when she went home. She said her shot was at 8:45 on the 22Mar2021 and the symptoms started 48 hours later. She said she was tired, she thought that's because there was a lot going on. She felt she was fine. She said the finger tingling kind of went away, she didn't know if it was because she became dehydrated. She remarked she was nervous, she thought to herself was she having a stroke, what happening? She wasn't attributing this to the shot, she wasn't assuming this was from the shot. She said that all ends, so now fast forward to Easter Sunday 04Apr2021 (as reported), that evening she was nauseous again, like that same feeling, she was going to go to bed, she was tired. She said it was at 3 am clarifying that technically this was on 05APR2021 early morning, she had severe stomach pain again, nausea, diarrhea. The Nausea was so bad that she was dry heaving for probably 5 hours but nothing was coming up. She said she didn't eat all that much and maybe it was because it was Easter and there was a lot going on and she wasn't feeling good. She said she had the cold sweats and tingling again, the worst was the cramps. She called her gastroenterologist who did her colonoscopy, she doesn't know if she had diverticulitis or what's going on, he said to go to the ER if she was in that much pain. She said she normally doesn't go to the ER for anything, but she was in that much pain that she went to the hospital, spent the day in the ER, they did tests, blood test, urine, X-Rays, they checked her all out and could not figure out why she was so nauseas, why she was having diarrhea, or why she was in pain, all the test came back fine, there was no infection and no obstruction, maybe it was gastritis. She said they say gastritis, that she had to relieve the stress in her life. She chuckles and wonders what caused all of this. The Nausea the second time was really bad, the first time it lasted couple of hours but this second time it lasted through the night even until she got to the hospital she was even carrying a bag with her because it was gagging her, it was that bad. When queried the outcome of the events the second time around after 05Apr2021, she at first stated that it ended pretty much, but then stated no it didn't end, the stomach cramp continued. They prescribed Zofran for nausea and Bentyl for the diarrhea. She does not know the mg dosage of Zofran and Bentyl. She said she just had to go pick up another thing, her insurance . She looks at her information. She said basically it was the same as before, she just didn't know, they didnt know what was wrong, they didn't even ask if she had the COVID shot, she didn't tell them and they didn't ask. She said for her it was a mental game, so many dates were close to her husband's passing, she wasn't stressing out, her doctor did not think that was what it was, she doesn't feel like it was. She said her doctor said she needs to call, something is going in. She said she took the two medicines for 5 days and they relieved her.
