She received her booster dose on Friday, so that was her third dose. She has a lot of information. She said her first and second dose were fine with nothing major. She just had swelling in her armpits that was for the first and second doses. On Saturday after her booster dose, she didnt have much with an appetite and she has muscle aches and joint pain. Sunday, she started feeling like she was having contraction like she was going to deliver a baby every five minutes. She said it was severe pain and started getting worse and worse and was happening every two minute and said it was abdominal pain like she was getting stabbed by knife. She said she went to the ER thinking that she will die because of the severity of the pain. She said it wasnt stone there was not nothing like its fine and she thinks it her body, certain reaction to the vaccine and then her lymph nodes were going to explode. She said, she couldnt move her left arm. She repeated that she thought she was dying, and thought may be the lymph tissue and her body was inflamed. She said her intestine stopped moving and it was not until Monday that she couldnt pass a bowel movement and she said she started feeling better on Monday her lymph node going smaller on her armpit. She said she still have some abdominal pain, but everything is coming down and she said the abdominal pain was unbearable. She still has excessive sweating and having night sweats.

When Paraphrased the concern, consumer stated,Correct, booster dose. Yes. They had to do for me a CT scan they had to get Iodine contrast (further clarification unknown), so she thinks that are going unnecessary for her, but because this pain was unbearable. So, she did not have gone to the EV, So she wanted to show them how bad it was. she dont find anything they give me injectable medicine, pain medicine, oral medicine and she was on them around the clock. Last night was the only time when she didnt take medicine so now, she thanks God she was still alive, so she just wanted to let them know that this abdominal pain that comes as a side effect is bad.
