Too long to have muscle pain from a shot; Migraine headache; severe arm pain where the shot was injected; This is a spontaneous report from a contactable consumer (patient). A 72-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE; lot number: EL9261; expiration date not provided), via an unspecified route of administration from 21Jan2021 to 21Jan2021 at SINGLE DOSE for an unspecified indication. Medical history included 'thyroid' from an unknown date and unknown if ongoing. Concomitant medication included levothyroxine from an unspecified date and unknown if ongoing at 100 ug, 1x/day for 'thyroid'. Patient stated that she spoke with her physician's assistant. Patient received vaccine on the 21st of January, the first shot at her local place. The following morning at 4 in the morning, patient had severe arm pain where the shot was injected. So patient put a hot compress on it and took some paracetamol (TYLENOL). Patient mentioned that it didn't relieve for about an hour and a half. Patient meant the pain was really severe but finally it went away. The next day, it came back again and then the patient did it again and the pain keep coming back. Patient stated "And now it's been tomorrow will be a week. And that's too long to have muscle pain from my shot". Patient also mentioned that second day after the shot, migraine headache started. Patient stated, "Now I get them, but I only get them in the spring and I get them in the Fall. I don't get the migraine headaches in the winter time. I could only take Excedrin Migraine for the migraine, it's just over the counter medicine. And so I took that for the headache but those have not gone away either. When patient contacted her physician's assistant just now, it was reported that patient the physician's assistant is going to write a prescription for a muscle relaxer. Patient also reported that she is not going to take that second shot as she didn't know where to go to cancel it but she is not taking it. Patient mentioned she can't have pains like this. Patient stated that she can't tolerate pain to begin with, let alone have excess pain in her system. Patient added that she doesn't take medications. She is only on a thyroid medication (later confirmed the name as levothyroxine). Patient confirmed that the vaccine was Pfizer COVID-19 vaccine. When probed for the due date of the next shot, patient stated 'February 11th at 12 o' clock'. Patient also stated 'I am not getting it, I am not taking the second shot. I didn't get you, I don't know what you said. I am not understanding you. I am not getting what you are saying. I am not taking the second shot, it is scheduled for February 11th of 2021, I am not taking it. Because they called and asked if I wanted to receive it and my age is almost 73. So, I thought I probably should give it a chance. But now with the reaction I don't want the second one' and 'I don't know if there is something wrong with this phone or something wrong with the connection, I don't understand, I get part of it but I don't understand the other part. It blanks out, I don't know what's wrong, you are asking me something, but I don't know what it is'. Patient also reported that the pain started the day after she got the shot, 22Jan2021. Patient is still having pain. Patient also confirmed that TYLENOL was the treatment for pain but it was not working. Medication for migraine was reported as EXCEDRIN migraine. Patient further confirmed EXCEDRIN Migraine did not help with the migraine and stated 'No, I still have it, it gives me some relief but then after wears off it comes back, the migraine comes back'. Patient further added "Okay, I am just going to rely on my physician assistant, she has got some medication ordered for me, a muscle relaxer. And I am going to try that and see if that will make everything go away".  Outcome of the events 'severe arm pain where the shot was injected' and 'migraine headache' was not recovered; outcome of the remaining event was unknown.
