Additional information: ER nurse on the line that got her 1st dose of Pfizer Covid 19 vaccine on 11Sep2021 and she felt sick in less than 24 hours after the administration. Caller mentioned that the headache was tolerable on the first few days but after 5 to 6 days, headache got more severe and turned to migraine. Caller also mentioned that she experienced the AE for 3 weeks and about 6 days ago, her neck started hurting and described it as more of a neck bone pain going down the muscle, and more on the right side which was also the same side where she got the vaccine shot and went up onto the base of the skull and stated that she had been taking anagram and Tylenol. Reporter was not sure that he captured that correct. Caller also stated that she did not feel any swollen lymph nodes. Caller stated that the pain in her neck was right above where her shoulders were to the base of her skull and came down more on the right side than the left. Stated that she did not know if the migraines were getting that bad. Stated that her 2nd dose was due (next dat to the report on 01Oct2021) and this headache was ridiculous. Stated that she had Covid pneumonia for 5 weeks and she only had a headache with the Covid and this was not the same now with the headache and it made her kind of nervous. She had brain fog and memory issues with Covid and those were finally clearing up and she was hesitant to get it (next day of the report) as it's been 3 weeks. The headache went for 5-6 days and then she got a day where she did not have to take anything. Stated that last night she took 1 gram of Tylenol and 800 of ibuprofen at the same time and put heat on her neck to function, that was the only way to make it go away. It wasn't 100 percent gone but got almost there and then came back. She got stress related migraines, has had 3 over the last 3 years and they were not frequent at all. Caller stated that it's bothering her, it's so constant. Stated that she got the vaccine about 10:20-10:30 am and at 2 am she woke up with cold sweats and really sick until midnight. Stated then the headache came and it had just gotten progressively worse. Stated that she had body aches and during that period it felt just like she had severe flu which was to be expected. Stated that she got the hot and cold sweats when her neck pain got bad and she had that with Covid. Stated that she had Covid for 5 weeks and when she was sick she got better was she was waiting and waiting for it to get better and it's worse. Stated that last night she had a severe headache she had to take medicine it was so bad. Stated that she had only been taking medicine 2 times last week but last night and the neck pain was super bad 6-7 days ago. Stated that it was not like meningitis but it was so stiff from pain that she couldn't get her chin to her chest and she was freaking out a little. Caller stated that she was on leave from work and had done nothing strenuous to hurt her neck and it's nothing related to an injury. Caller stated that her neck was still stiff but she could touch her chin to her chest at the time of report and move it but it's still there. She had her antibodies checked 2-3 weeks ago before and it was over 2 from having Covid but she works in the ER and she was supposed to go back next week and wanted to get vaccinated before she went back but she did not know. Caller declined to make a report. Caller stated that she already had her own antibodies and then reacted to the vaccine so she was nervous for the 2nd one. Caller stated that she did not want to cancel but she may have to as she was nervous with the headache being so constant, that some people say the 2nd dose was worse and some say the 1st was worse, that everyone was different. Caller stated that her card was hard to read the lot, the writing was very loopy. Stated that it says E and it's either U, W, or V and 0191.  This follow-up is being submitted to notify that the lot/batch number is not available despite the follow-up attempts made. Follow-up attempts completed. No further information is expected.
