It was reported that in March, the patient had received a Moderna Covid shot, which had been administered in her upper left buttock. She reported that a large welt had developed there and had lasted for about a month, causing significant soreness. She noted that this soreness had led to hip pain, which she had not experienced before. Seven months later, she stated that the pain was still present and occasionally woke her up at night, including on the night she wrote the message. She expressed a need to find out whether any research or data existed regarding this issue and inquired if others who had received the shot in the upper buttock had also developed hip pain. She requested any relevant information about similar cases or possible treatment options. She mentioned that she was consulting with her primary care physician and planned to follow up with an orthopedic doctor but hoped to obtain information directly from Moderna in the meantime. She acknowledged that the hip and buttock pain might have been caused by the vaccine she had received in that area, especially since the pain had started immediately after the vaccination. However, she admitted that she was not certain and did not pursue the matter further. She added that she did not want to place the burden of researching the issue on her healthcare provider, which was why she had decided to contact the company directly. It was unknown if the patient experienced any additional symptoms or events. Treatment medication was not reported.
