Her shot was supposed to be at 10:45 but because she was getting it in her right arm it was delayed, so it was probably around 11:15.

Medical history included high blood pressure, anti-cancer, GERD (Gastrooesophageal reflux disease), double mastectomy and was post chemo, hemochromatosis, breast cancer.

She got the second shot around 11am on a Friday and woke up at 2:00am and felt like she was hit by a truck. She had muscle aches and pains, extreme fatigue, difficulty walking. Then about 14 hours later, everything was gone. Patient received her booster dose "today" (on 29Oct2021). She stated by the time she got to her car, she had soaked through the cotton ball that the administrator of the vaccine had applied after the injection. Patient noted a lot of bleeding. She believed that the one who gave her vaccine may have hit a "blood vessel" and it went into the "vein vs the muscle. Patient did not feel as though it was administered IM or any clotting effects. Patient noted her arm was warm to the touch with a hematoma underneath. She would also like to know what Pfizer recommends, whether it be a warm compress or cold compress for hematomas at the injection site. Patient stated that they "pinched up my arm" and she felt as though if the skin were pulled taunt it would have been better based upon her anatomy/body. She had grabbed paper towels because there was a lot of bleeding. This happened around 11:00AM and now (as of 29Oct2021) there was bruising. The person administering the vaccine didn't aspirate. She believed the person pinched up on her skin, she wasn't paying attention. She believed the person administering hit a blood vessel for it to cause that much bleeding. After the third dose, she has bleeding and bruising. She sent a pic of her arm to her friends and they responded asking what it was. Her arm and shoulder hurts, it's already bruised. She clarified there was a hematoma, the area was warm to touch, and there was a hard lump underneath. It's not a typical reaction to an injection. She was sure it was due to technique.

She stated the event being medically significant had yet to be determined. She did not need a trip to the ER, she was just watching for any signs.
