The patient underwent the following laboratory tests and procedures: blood pressure measurement: low; full blood count: showed lot platelets; platelet count: low itp, notes: 4 times and every time it was low ITP; ultrasound scan: no dvt, notes: both showed no DVT.  Clinical course: The patient has been administered 2 doses of Pfizer Covid-19 Vaccine and while she was departing after getting the vaccine she felt her blood vessel was not acting right and her lymph nodes are swollen as well regarding what she has experienced since being administered the Pfizer Covid-19 Vaccine doses. She further described experiences as starting the night she received the Pfizer Covid-19 Vaccine which was on her left side, she felt kind of tense or tender, like lymph nodes were swollen and her blood vessels felt uncomfortable for like 1 week. She felt like her blood vessels were not acting right, she feels like the blood vessels are kind of moving inside and then sometimes she feels pain in the blood vessels. She has never had these feelings before. She clarified that her lymph nodes are kind of swollen, but they are kind of always like that. After that first week she kind of has the events with her blood vessels a lot; then later on about maybe in September something happened where she suddenly felt her blood rushing kind of in her blood vessels. She has seen her family doctor multiple times regarding these events and the family doctor has done a lot of blood tests repeatedly. He wanted to see if she has ITP. She also reported that the first week she felt on the left side her lymph nodes were (big) and her blood pressure is low. After one week it disappeared but since September she feels the blood vessels in her feet and leg and hands feel pain. It is usually more on the leg. She stated she checked with her doctor and he did a test and didn't freak out. They suspected a blood clot and they checked her and it was not. They did a DVT ultrasound twice because the blood vessels were very painful in her leg so they did this in September. Then recently her leg was swollen and warm in one leg and they did another ultrasound but both showed no DVT. She said she can show it is kind of moving, she can feel the blood vessel inside. She does not know why the blood vessels after the vaccine on her feet and hand feel pain suddenly like a jump pain. She has never had this problem. Her doctor did a lot of blood draws. He repeated the blood platelet 4 times and every time it was low ITP. The blood count only showed lot platelets. The doctor told her to see a hematologist. She feels pain at night when she lays in bed but it is getting more and more. 2 weeks ago she got cellulitis but that leg started to feel like a "jump" in the blood vessel. She takes an antibiotic, Clindamycin, and an antiviral. She stated yesterday she was at the end of her Clindamycin. It has a lot of side effects because the medicine is strong and she has loose stools. She stopped the Clindamycin yesterday but the day before when she was still on it she felt the blood vessel was moving and pain. So, they stopped that because of the side effects. It is getting worse. Her friend told her she has prediabetes but after 6 months she does not have diabetes and that within 6 months of the vaccine the tests are not accurate.    The lot number for bnt162b2 was not provided and will be requested during follow up.
