The patient was treated with Doxycycline at an unspecified dose and frequency. At the time of the report, PAIN (I got a burning sensation and pain) and BURNING SENSATION (I got a burning sensation and pain) had resolved and DYSPEPSIA (heartburn), GASTROOESOPHAGEAL REFLUX DISEASE (acid reflux) and VACCINATION SITE PAIN (pain in what the shot where I got the Moderna shot) outcome was unknown.      No concomitant medications were reported.  It was reported that patient had a weight of around 103104 lbs, and she had been 5 feet tall. She also reported that, due to having many allergy issues, it had been very difficult for her to distinguish them from a normal reaction. She had received a couple of Moderna shots, with the last one administered in late September or early October of 2024. She reported that she had known it had been "banned" because she had visited her sister in another state.She had received the shot and, upon seeing the actual vaccine and the needle going into her arm, had experienced a burning sensation and pain. This discomfort had lasted intermittently for around 33 weeks before subsiding. Then, moving forward to late March or early April, she had not had the data on her regarding a visit to the doctor but had been prescribed medication, of which she had taken one pill and had subsequently experienced heartburn and acid reflux. She had also taken Doxycycline, after which she had contacted the doctor's office and discarded the pills.She had reported that she had not been sick until the time of reporting; however, she had mentioned that, in the past, she had taken Z-Pack Erythromycin tablets, for which she had obtained a prescription that had been filled on April 4th or 5th. She had been uncertain but had reiterated that it was likely the 5th when she had taken only one of the tablets, which had caused her to have a very severe reaction. It had been the same reaction she had previously experienced when she had received her first COVID-19 shots at the beginning of the pandemic, during which she had "taken" two namely, the two original Pfizer vaccines and the second Pfizer vaccine.
