The patient's current conditions included asthma and allergies. The patient's concomitant medications were not reported.  On 12-Sep-2021, the patient was vaccinated with Flucelvax Quadrivalent (influenza vaccine inact sag 4v; dose, route of administration and anatomical location: not reported) for influenza prophylaxis. The batch number was not reported. The patient stated that her company makes her get a flu shot.  On the same date, as soon as she received Flucelvax Quadrivalent, the patient developed massive internal chest tremors, that was like a cell phone was on vibrate going off or a washing machine was running inside her chest night and day. She was experiencing this everyday. The patient was prescribed propranolol as treatment for the massive chest tremors. The patient was also experienced hand and neck tremors, muscle jerks, and electrical shock pains all over. The patient stated that she never had this before she took this shot. The patient's gastrointestinal (GI) system just decided to stop and her GI issues are off the charts, and it has been a living nightmare ever since. The patient also had a shoulder injury from the vaccine.  On an unspecified date, an unspecified time after receiving Flucelvax Quadrivalent, the patient visited her physician's office and was diagnosed with arthritis and was given gabapentin as treatment for the shoulder injury and arthritis. She was given magnetic resonance imaging (MRI) and computed tomography (CT) by her doctor to rule out an aneurysm for some of the symptoms that she was experiencing. The patient did not understand why they were looking for an aneurysm because she was worried about the freaking crawling around her head that felt like there was a parasite living off of her brain matter. The results of the MRI and CT were not provided.  At the time of initial reporting, on 28-Jun-2022, the patient did not recover from the events. The patient was extremely frustrated and stated that she has spent over thousand dollars to figure out what has been going on since she received Flucelvax Quadrivalent last year and started experiencing all of the issues she was currently experiencing and no one was helping her. She was looking for guidance stating that none of the medical groups care if you have a vaccine injury or not and they have been told not to deal with this. Any of these medical institutions that have a research or education arm, the large medical groups, they are beholden to the federal government on what their Food and Drug Administration (FDA) or Centers for Disease Control and Prevention (CDC) tells them to do. The system could care less. So she was not going to get any care, sign off, or any of that from an actual PCP. She has already been down that road. It was a dead end. She asked for a full listing of ingredients in the Flucelvax Quadrivalent. Upon receiving the location and listing of full ingredients, she requested to know what 'other proteins than HA' means, that she has allergies and would like to know what these proteins were.  The reporter assessed the events as related to Flucelvax Quadrivalent. She stated that she was having a reaction and was suffering ever since receiving Flucelvax Quadrivalent, very similar to all of the people describing their COVID-19 shots adverse events, as reported, her events were parallel to them.  This case was assessed as non-serious.  Company comment: A female patient of unspecified age was vaccinated with Flucelvax Quadrivalent.
