3/26 @ 3:15pm ? Got the first dose of Pfizer COVID-19 vaccine for the 1:10pm appointment. However actual time received was around 3:15pm. No vaccine reaction was observed and drove back home. However did not eat or drink much from morning till 4:30pm due to the long line at the vaccination center   4/4 @ 9:00pm ? Experienced first sign of near-syncope at the dinner table upon picking up a glass of milk  4/6 @ 8:45am ? Experienced brain fog, to be exact head felt like it was filled with cotton candy, at the back and top of the head. Felt this way the entire day. Went to work as usual. Logged out at around 5:30pm  4/7 @ 9:00am ? dizziness started getting worse. Started feeling imbalance and started losing depth perception which climbing down staircase  4/8 @ 10:00am ? started to get easily startled by any unexpected trigger. Whole body would ?twitch? or ?startle? upon slightest unexpected event. For e.g., sound, touch, taste (hot/cold)  4/10 @ 12:00pm ? Went to ER. ER ordered series of book tests, EKG, chest x-ray. Everything came out normal. ER doctor said to wait it out and after a week symptom may go away. ER doctor felt body?s immune response was over-working due to the vaccine immune response and possibly pollen allergy I may have experienced right after getting the vaccine. No prescription meds give. Advised to take Meclizine 25mg and Zyrtec. Below are the symptoms experienced on 4/10:  ? Lightheadedness/Sudden Jerking body movements when triggered/passing out momentarily for a second when taking strain/not in my elements ? Feeling extremely fatigued. Did not sleep well at night on 4/8 and 4/9 ? Head feels Intoxicated, foggy, lightheaded, as if stuffed with cotton candy. Startled when unexpected things happen like a sudden jerking movement along with momentary passing out while anything unexpected happens. E.g., when I am pushing myself on the sofa to re-position, I feel my whole body is turning off for a second. Simply does not feel normal ? Rubbery legs ? Worsens after shower. I feel like I need to lay down as the foggy feeling worsens after shower ? Lightheadedness. Losing control sometimes. ? I am easily startled when climbing down the stairs - no Depth perception. ? Don?t have the strength to blow nose or cough. Feels like momentary fainting when doing these activities ? Dis-equilibrium. Whole body is twitching when something unexpected happens to my senses. ? Unable to control while laughing feels like momentary faint. I have felt like this when I was down with a fever. Tickled easily ? Difficulty pulling myself out of bed. Felt like muscle was giving away ? Tingling feeling in the right abdomen area ? Difficulty staying alert or focused and random rather unpleasant thoughts constantly coming to mind. Felt a bit of panic attack.  4/11 ? Went to PCP. Body weakness and fatigue got worse. PCP did blood sugar test and flushed out the left ear. Ordered Brain MRI to see if structurally anything was wrong. Brain MRI came out OK as well however noticed minor sinusitis. Prescribed Amoxicillin antibiotics and nasal spray. Referred me to Neurologist and Head and Neck Specialist.  4/11 ? 4/15 - Above symptoms progressively got worse. Especially weakness in the arms and shoulders. Arms quivered every time trying to stand up and felt like fainting. Hand-eye coordination progressively got worse. For e.g., could not pick up water bottle, hands were quivering badly  4/15 ? Neurologist conducted certain diagnostic tests and concluded that there are no neurological issues. Said with rest and plenty of fluids it should get better. Spinal tap was not recommended and said if symptoms got worse a spinal tap can be done during the next visit. Follow up visit with neurologist scheduled on 4/27  4/15 ? 4/27 ? Weakness in arms got better. Arm strength and coordination has improved however it?s still not back to normal. Brain fog and dizziness still persists with no improvement. Left limb and arms are stronger than the left. Difficulty climbing up and down stairs. Dizziness worsens after shower. Not feeling myself. In addition, not able to multitask - getting startled and need to be deliberate about having to do everyday chores need to just focus on one task 100% completely and if something else comes up then my body just goes into a momentary shock. Mostly I can feel my head feeling heavy and my eyelids shutting down when something shocking happens ? a feeling like body is ?turning off?, almost a fainting or passing out feeling. Sometimes when I turn to one side and sleep, I can feel a flickering sensation in the ear. Still always feeling woozy and as if there is something in my head ? a medicated or intoxicated feeling in the head  4/27 ? Neurologist said she sees a lot of improvement and reiterated again that I don?t have any neurological issues. She said I can go back to work starting 5/1. She said I may have Conversion Disorder / Disequilibrium. It?s hard for me to fathom why she would diagnose me with Conversion Disorder when so many people are reporting very similar symptoms that I am facing on the below forum: https://www.drugdiscoverytrends.com/dizziness-among-common-covid-19-vaccine-side-effects/  4/30 ? Next appointment with Head and Neck / Audiology
