A 74-year-old female patient received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration, administered in the left arm on 22Mar2021 (Batch/Lot Number: ER8750) as SINGLE DOSE for covid-19 immunisation.  Medical history included ongoing nerve pain and nerve damage: she said that 10 years ago, in Oct2011, she had a reaction to the flu shot, she woke up with burning in her kneecaps of both knees, just in the kneecap, the patella area only.  She says she had an allergic reaction to the flu shot and it has changed her immune system, in 2011, the nerves in her knees, she has had so many procedures. The flu shot was a live toxin in 2011, so she has some apprehension about getting the COVID shot. She had this adverse reaction to the flu shot 10 years ago then got the disease where you're bitten by a tick, she was diagnosed with lyme disease in Oct2011 (the Lyme disease goes back 10 years); she had that tick, where she was bitten by a tick, she has a lot of pain in her knees, terrible nerve pain. She says she was told by her rheumatologist to maybe wait until pain under control to get the shot, but it has not been under control for years. She said she had lots of doctors but her primary care provider, her rheumatologist was her main doctor for nerve damage. Concomitant medications included gabapentin (GABAPENTIN) taken for neuralgia from 2013 to an unspecified stop date.  She says she takes a lot of medications. She says her Gabapentin was increased from 2700mg to 3000mg after her reaction, she takes five 600mg pills a day, she is so healthy, but this nerve pain has changed her life. On 25Mar2021 (also reported as 30Mar2021), after the shot, gradually the nerves were on fire going all the way up and down her legs, both legs, she was in so much pain and was reported as worsened. She says she had no immediate reaction, but then the pain got worse and worse, she could almost feel. She said she had to get a colonoscopy, and have to do the prep, but she cancelled it, it was scheduled on 9am on Friday 26Mar2021. On 30Mar2021, she ended up in the emergency room due to an allergic reaction. Nobody goes there unless you have to, you'll have to wait 4 hours, she sat for 4 hours. She says she was not admitted to the hospital, she went to the emergency room because on Monday, 29Mar2021, she finally she emailed her doctor, she could almost feel her chest and her gut area quivering, shaking, that's when the doctor said to go. Then on 30Mar2021, she went to the emergency room in (Withheld) because all her nerves were on fire, it was running down her knees, legs, and in her abdomen. She says she emailed her doctor early, she didn't know what she was going to say, she needed to go to the ER to get her nerves evaluated, they didn't know what she was talking about, she showed them her email, her rheumatologist is really good, they didn't admit her but they did set her up for a neurologist for the 12th, the ER doctor said she couldn't do anything for her and they referred her to a neurologist, she did put her on high doses of prednisone. The prednisone is 60mg, she had 2 pills in the hospital then for the next 5 days she took 40mg to settle the nerves, she threw the bottle away, she says she can get it if we need it. She says the prednisone helped, she took 2 pills on the 30th and picked up the pills the next day, the 31st. She says she's sure she has the little thing, it says Prednisone 20mg tablets take 2 tablets by mouth once a day for 5 days. She asked if she should get the second shot or just the first one, and how covered is she with just the one shot. She was recommended not to take the 2nd dose of the covid vaccine as scheduled on 21Apr2021 by doctors.
