sluggish; dizziness; legs felt like lead after the first dose; This is a spontaneous report from a contactable consumer (patient). This case is for the events associated with the first COVID vaccine.  A 68-years-old female patient received first dose of bnt162b2 (BNT162B2, PFIZER-BIOTECH COVID-19 VACCINE, Solution for injection, Lot Number: EW0158), via an unspecified route of administration, administered in arm left on 20May2021 (at the age of 68-years-old) as single for COVID-19 immunization at hospital. The patient did not have any medical history. Concomitant medication included paroxetine hydrochloride (PAXIL [PAROXETINE HYDROCHLORIDE]) 20mg daily at night from Sep2012 and ongoing (was unable to handle having her husband leave her, it also makes her sleep well). There was no history of any previous immunization with the Pfizer vaccine considered as suspect. The patient did not receive any vaccine on same date of the Pfizer suspect or within four weeks prior to the first administration date of the suspect vaccine. The patient took COVID vaccine as she had a few friends that have a bad immune system and she wanted to be around them and others. On 21May2021, the patient experienced sluggish, dizziness and legs felt like lead after the first dose. The patient reported that she was not positive, but things happened to her after she received the first shot of the COVID Vaccine on 20May2021. On 21May2021, she was outside cutting the grass. It was hot outside. She started to feel sluggish and was dizzy. Her legs felt like lead. She stopped cutting grass and went inside and drank fluids and she felt better. She thought she might have drank gator something. She received the second dose on 10Jun2021. She slept that whole day on Friday and Saturday. After waking on Sunday, she had a lot of pain in her stomach for a few days after eating certain things. She continued to feel sluggish and dizzy after the second dose and had stomach pain.On Wednesday, she got tired of it. She checked herself into the emergency room as advised by the doctors office. She was told not to go to the urgent care. She thought she would go home but was admitted. Her hemoglobin was 7. Normal for women was 12-13. She was very close to having a transfusion. She had X-rays and an Ultrasound. Those indicated that she had a hiatal hernia. She was still having blood problems. She would be having another test. One result for her hemoglobin was 7.1 then it was up to 7.9. The feeling sluggish has improved because she stopped doing any heavy lifting. She is not saying the vaccine did it. She has been healthy until now. She does not take any prescriptions except Paxil. She takes that because her husband was having an affair and left her after 40 years of marriage. Her blood pressure has been good. But this is like a domino effect. She also had an upper GI. The doctor that did that said all of this was weird timing. He thought this was all unusual. She was fine the day she had the vaccine until she cut grass. She was unsure what she ate. The pain was higher up and went from side to side and would go around to the back. She was put on medication. When she was in the hospital, she did not eat anything due to having tests until that Friday. The events required a visit to emergency room. The patient underwent lab tests and procedures which included haemoglobin: 7 on 23Jun2021, haemoglobin: 7.1 on 23Jun2021, haemoglobin: 7.9 on Jul2021, upper GI: unknown results, ultrasound scan: unknown results and x-ray: unknown results. The outcome for the events was resolving.  Follow-up information has been requested.
