Blood clots; terrifies me; serious concerns; My hands suddenly started tingling; My feet started to feel as if they were gnarling up; My finger tips were blue; This is a spontaneous report from a contactable consumer.   A 77-year-old patient of an unspecified gender received the first dose of bnt162b2 (BNT162B2, Lot Number: FD8338), via an unspecified route of administration on 24Aug2021 as a single dose for COVID-19 immunization.  Medical history included COVID-19 (reported as "was a COVID long hauler"), an unspecified illness (reported as "I became dreadfully ill") from an unknown date and unknown if ongoing at the time that COVID 19 was just becoming known between Christmas 2019 and New Years 2020, cardiac disorder ("serious heart condition") from an unknown date and unknown if ongoing, tingling feet/hands, skin discoloration (reported as "finger tips and toes would turn blue"), foot discomfort (reported as "my feet would gnarl up"), blood pressure high, dental crown procedure, hypercoagulation (reported as "instant coagulation" after cutting leg shaving) and small cut.  Prior to the "hypercoagulation" the patient also reports always having had a strong blood flow (reported a "to the point that people would ask if I was a haemopheliac").  The patient's concomitant medications were not reported.  The patient experienced blood clots  which was medically significant on an unspecified date with outcome of unknown, my hands suddenly started tingling on 24Aug2021 with outcome of recovered, her feet started to feel as if they were gnarling up on 24Aug2021 with outcome of recovered, her finger tips were blue on 24Aug2021 with outcome of recovered. Further description of what happened after vaccination (reported as "35 - 40 minutes later") was reported by the patient and is as follows:   "About 30 - 45 minutes later my hands suddenly started tingling. My finger tips were blue. Then my feet started to feel as if they were 'gnarling up.' This lasted for about 30 minutes and suddenly the tingling blue tips went away and I have been fine since. This seriously concerns me because at the time that Covid 19 was just becoming known between Christmas 2019 and New Years 2020. I became dreadfully ill. Among other things my finger tips would tingle and turn blue. My toes would turn blue and my feet gnarl up to where they didn't really look like feet.  The tingling blue fingers situations took place every day lasting for about 4 hours, then suddenly disappeared. On 03Jan2020. I picked up my prescriptions for a serious heart condition at withheld The Pharmacist didn't know what to make of it. Then I cut my leg shaving and I didn't bleed. Previously, I have always had a strong blood flow to the point where people would inquire as to whether I was a haemophiliac. When I went to the dentist for a routine check up my fingertips were tingling and blue. The dental assistant took my blood pressure. It was over 180. About 15 minutes later the tingling stopped. I had her immediately check my blood pressure which had suddenly dropped to 120.  Over time the tingling and blue tips slowly dissipated. When I saw my primary care physician (Dr. withheld) she was convinced I was a COVID long hauler. News reports had begun to show much younger people developing blood clots with COVID, experiencing the same gnarled feet and tingling of fingers. I could not understand why, at 77, I experienced the same reactions as people 40 years younger, but did not die.  Although I was no longer experiencing tingling and blue tips if I skinned my knee, cut my leg there was no bleeding, just instant coagulation. In Jul2021 for the first when I received a small cut, there was a tiny flow of blood. I was thrilled. Because of blood clots I had been wary of taking any COVID 19 vaccine. However, the tightening of rules that you have to be fully vaccinated to enter certain places caused me to inquire about the vaccine. My doctor's PA said he couldn't advise. I would have to make my own decision or ask my pharmacist. The druggist said he couldn't advice but they gave two types and if I decided to get it, he'd recommend Pfizer. He also advised drinking 'lots and lots of water.'  I told him could not since I was restricted to consuming no more than 62 ounces of including liquid in food in any 24 hour period. I decided to get the first dose (FD 8338) and experienced the same tingling and blue tip side effect that I hadn't experienced in a year. That terrifies me." No lab data was reported.  Treatment information was not reported.
