A 43-years-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), via an unspecified route of administration in the right arm in the morning of 01Apr2021 (Batch/Lot Number: ER8727) as a single dose for COVID-19 immunization. Medical history included ongoing complex regional pain syndrome, ongoing fibromyalgia, ongoing arthritis - all diagnosed 20 years ago. Her mother has lupus and rheumatoid arthritis and she can't have the vaccine, states she doesn't know if something could be genetic. Low potassium in the past and stated that she has a lot of allergies to medications, but she consulted with the pharmacist and he said it would be okay. There were no concomitant medications. No additional vaccine was administered on the same date of BNT162B2 and no prior vaccination within four weeks. The patient was having weird symptoms and she tried looking online and in different groups to find out if anyone has similar symptoms, but she hasn't been able to find anything. She began by saying she has health issues; she has Fibromyalgia and Complex Regional Pain Syndrome. She doesn't know if studies were performed on patients with those disorders that took the vaccine. It's been about 3 weeks since getting the vaccine (Apr2021) and she started having symptoms that she thought could be a blood clot. From the knees down, she was having a lot of pain, cramps, burning from her calf to her feet. She would keep rubbing them and massaging them. It was excruciating pain. She was having symptoms and she did go see her Nurse Practitioner on 14Apr2021 because she thought she was having a stroke or a clot or something in her legs or that she was having a problem with her cholesterol. The nurse thought maybe it was her electrolytes, because she had low potassium in the past, but everything came back normal. Her feet were painful but not as bad in Apr2021. She felt like her condition but it's flaring up like 200% it's like over a 10 on the pain scale. She can't think right, she can't work, and was very uncomfortable in Apr2021. The leg pain felt like it is really deep in the vein, it doesn't feel like it is superficial, and she can feel stuff or liquid flowing. Her pain alternates from her head to her neck to her feet and it is very uncomfortable. Her hands and feet started to go numb, not completely numb but like when they fall asleep from sitting on them and then hit something and it hurts. Her arms were burning like crazy; they itch, they burn in Apr2021. Different temperatures like hot and cold make it painful, bad and irritating, and she can't sleep well because of her symptoms. She doesn't know the exact dates, but it has been about a week, but it is changing. It started with cramps in her legs from her knees down. That is where she had injuries and she thought it was her cholesterol. From her knees down, she has cramps and pain and it is very uncomfortable, she felt a really deep pain. She has pain in her neck then to her back, it started in her lower extremities and it is going up. It has stayed the same and she has to keep taking Tylenol to control the pain. Her symptoms got worse and she started taking Tylenol and that helped and then on 15Apr2021, her hands and feet started going numb and she had a headache and pain on the top portion of her head (reported as brain) and her hands hurt, and she was nauseous. She hasn't heard back from the nurse practitioner, so she decided not to go and get it done because she felt it is from the vaccine. She also has swelling of feet in Apr2021, and now she just woke up an hour ago and she slept somewhat okay, but she had to take Tylenol. Now that she is standing, it felt like her legs are starting to hurt again. Treatment included Tylenol, which helps a little and she has to keep taking it. If she doesn't take Tylenol, she can't even function. The events from the knees down I was having a lot pain/leg pain felt like it is really deep in the vein, cramps, my hands and feet started going numb, they itch they burn, feet are painful, uncomfortable, pain on the top of my head and my hands hurt/headache, swelling in her feet, nauseous, pain in her neck then to her back, different temperatures like hot and cold make it bad and irritating had not resolved, while the event can't sleep well because of her symptoms was resolving, and the outcome rest of the events was unknown.
