Lower back pain; This is a spontaneous report from a contactable consumer. This 68-year-old female consumer (patient) reported that she received her second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Batch/Lot number: UNKNOWN) via an unspecified route of administration on 15Mar2021 as single dose for COVID-19 immunisation. The patient medical history and concomitant medications were not reported. The patient previously received her first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Batch/Lot number: UNKNOWN) via an unspecified route of administration on 22Feb2021 (at the age of 68-year-old) as single dose for COVID-19 immunisation. On 24Jun2021, the patient experienced lower back pain. Outcome of the event was resolved on an unspecified date in Jun2021.  She got the second Pfizer COVID vaccine this past March. Last Thursday the caller had lower back pain and went to urgent care and she might have received a lidocaine injection and a steroid injection for her pain. She did not experience any problems afterwards other than relief. She confirmed her 2nd dose of the COVID vaccine was in Mar2021. She says that she was a little shocked because the letter she received is a little scary. She was telling her husband that the only thing that she experienced with the lidocaine and steroid shot was relief. She does not know why they sent this letter. Maybe there was an issue but she has not had any other than trying to get over her muscle spams which are 95 percent gone and she does not know what to think about this letter. She might have received a lidocaine injection with a recall. She confirmed that her COVID vaccine did not have anything to do with her lower back pain because she has experienced lower back pain off and on annually since she retired from the air force so that COVID vaccine had zero to do with that. She did not experience any side effects from the second dose, it was easy breezy but the 1st dose took her down. She thought how she does not have a problem with her Pfizer COVID shot and that was months ago but then she saw on the letter it was for lidocaine. She remembered that she got two shots and then knew that the shot she got last Thursday must have been lidocaine but it does not have anything else on the letter. They did give her a letter when she left the urgent care and it is like a generic letter that what she got may cause drowsiness, avoid driving, do not drink and take ibuprofen. They gave her so many drugs that she would not take ibuprofen. She has been taking Baclofen, the muscle relaxer, and they also gave her tramadol and that is one that they need to take off of the market, it needs to come completely off, she took one and it made her sick as a dog. She had an upset stomach, throwing up and gagging. She only took one and it said do not flush the medicine and she did not flush it but she will never take it again. Lot Number: EG8933 and expiry date as 01Aug2022, she was given tramadol and that is one that they need to take off of the market, it needs to come completely off, she took one and it made her sick as a dog. She will never take it again. She said that the bottle says Tramadol 50 mg tablets and then it says Ultram 50 mg. It says take one tablet by mouth every 4 hours but she would have died if she had done that and taken one tablet every 4 hours as needed. Before you take any medication, they give you a book to read to tell about the side effects and all this but she read it because she thinks that it is important. She says that her tramadol is in a pharmacy bottle and discard after date of 24Jun2020 (documented as provided by caller). It also has something like 377 with a circle around it and it says quantity of 30. It did relieve the pain for her however the after effects are not worth it. She wo not ever take it again but she knows that everybody is different and maybe some people do not have those side effects from it.   Information about lot/batch number has been requested.
