Severe pain in my neck was really bad; Extreme head pain; Thyroid was totally messed up, way out of range; Joint pain; I am so bad; This is a spontaneous report from a contactable consumer (patient). A 56-year-old female patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, formulation: solution for injection, lot number: EW0167, expiration date was not reported), via an unspecified route of administration, administered in right arm on 10May2021 13:00 (at the age of 56-years-old) as dose 2, single for covid-19 immunization at hospital. The patient medical history included I had been sick from Mar2020 (I had been sick for few weeks she put me on like the steroid, Dose Pack and Z Pak (treatment)), I had a big rash from Mar2020 (I had a big rash she also put me on something Cream for the rash and felt within a week or 10 day, I was better), I had hypothyroid, I have a hardware on my neck like I have a plate and sixth screws and that also caused the same thing , guillain-barre syndrome (I have had a family patient with the, that had that of 'Guillain Barre syndrome'). Concomitant medication included pancreatin (CREON) taken for unknown indication from an unknown date. The patient historical vaccine included first dose of BNT162B2 (lot: ER8731) via an unspecified route of administration, administered in right arm on 19Apr2021 (at the age of 56-years-old) as dose 1, single for COVID-19 immunization. The patient historical vaccine also included flu shot (Got a flu shot back in, it was in September). It was reported that, Patient was calling to report that first of all patient first got diagnose in Mar2020 and her doctor had actually called CDC. She mean she had been sick for few weeks but she did not realize the symptoms until they asked about a rash and she had a big rash and she had gone to see her doctor just for a normal appointment and they called the CDC and they said send her for testing, so he wrote and order for lab work and they send me over there, when nobody had testing at that time and their office was telling her to go to the hospital. She go to the hospital, this is in Mar2020 and the hospital said well they do not have enough test unless you have severe breathing problems do not come to the hospital. And so 'much is that' and then in Dec2020 she got very sick again without any symptoms and she actually went and got tested and then it said negative but she felt sick just like the first time. She went to her doctor and so she put me on like the steroid, Dose Pack and Z Pak (treatment) and within several days, and then she also put me on something Cream for the rash and felt within a week or 10 day, She was better. But then she went and got COVID 19 shot and she got so sick. The first time was like 9 days and she was like if she have a better shot, it has to better than that but not the second shot and so she went and got the second shot and it was extreme head pain, she was so bad. She did not think she could get up and leave the waiting period and she waited in for extra 5 minutes and then when she got up she ask from the nurses and she said she really had head pain bad, is that normal. Oh yes headache is fine, so she went home but she had an extreme headache and everything for like 2 months after my second shot. And 2 weeks after my second she went to her doctors appointment that was already scheduled, for blood work and her Thyroid was totally messed up. She mean way out of range. She had always been on Thyroid medicine (Levothyroxine) for like a year but it was totally out of range (PC Filed Conservatively) and so they had to increase the dosage because she had hypothyroid (not captured as event). Patient further stated, the weird thing is she mom who lives in totally different state than I do in with-held. She happen to go for routine blood work also and she have been on the same dose for years and years and years under Thyroid medicine (Unspecified medication) and it was totally out of range and her medicine got increased also (hence split made). I wanted to report those symptoms because I think you know somehow, it was messing up the Thyroid and stuff.The first day she got the first vaccine. She have wrote down everything from the first she got the whole diary of it. On 19Apr2021 when she pretty bad symptoms for 9 days and then my second dose she  got on 10May2021. Then she have really bad symptoms from 10May to 20May. Currently because they increased her Thyroid medicine.  She have lost like 10 pounds in the past 4 weeks so she is currently at 112. Her first dose she got on 19Apr2021 (19Apr2021) and she got her second dose on 10May2021. She not only had severe, severe headache and it was not headache, it was a head pain but she also had severe neck pain like it went directly through the hardware in her neck. She mean that was weird and she was even wondering in how many participant has a lot of hardware in their neck. Patient was on my Levothyroxine for her thyroid which they really had to increase right after the first dose. She got back to the doctor on Monday to repack her thyroid because they tested it 2 months ago. Thats from her second shot that her thyroid messed up. It was actually after the first one they just said that it's a little bit of difference then she had blood work done but the second dose really big difference. Where they had to change my dose. The patient underwent lab tests and procedures which included Lab work (investigation): thyroid rose on an unspecified date, Got tested (sars-cov-2 test): negative on an unspecified date, Thyroid because they tested it 2 months (thyroid function test): unknown results on an unspecified date.
