DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 09-Dec-2024, Blood test: inconclusive..         No concomitant medication was reported. It was unknown if the patient experienced any additional symptoms/events. Patient recently (last week) received Spikevax and states that at that time within 3 hours all her major muscles started shaking. No pain, just twitching. Within 9 hours every major muscle in her body was in severe pain. Also reported vomiting/headache and she then seemed to get a little better. She slept for 3 days and describes feeling very sick. Then, at around day 3 (post vaccination), she was still having muscular issues and neurological issues where if she walks up a flight of stairs she felt as if she ran 10 miles and when that happens, she vomits because she was so exhausted from walking up the stairs. Also reported her muscles shaking. She stated that she received her vaccine on 03Dec (Tues) at 3:00 PM and by 6:30 PM she was experiencing these effects. She said she had video of her muscle's movements and twitching. She contacted her physician at that time (unclear what the advice was given at the time). She stated that her muscles were shaking and twitching upon rest. She stated that at the time of reporting (the muscles) were not at rest, if she walks up the stairs the muscles were extremely fatigued, and when she rests, they cramp up a bit. She stated the symptoms were actually worse. No treatment information was provided.
