About ten minutes after leaving the vaccination site, I began feeling a strange dizziness; an internal wobbly-Jello-like sensation. I felt a pin/needle/ stabbing sensation on my left fingers, particularly on the dorsal side of the third and fourth fingers, and in the middle of the tongue. The tongue felt as if was receiving a subtle electric charge that immobilized it with every shock. It lasted about 5 minutes. My vision was blurry. After that, my mind was foggy.  At about midnight, flu-like symptoms began sudden, but they were the expected symptoms for a covid vaccine (fever, body aches, sweats, sore throat, severe headache, pain on injection site, etc.) However, the pin/needle/ stabbing sensation was felt throughout the body. It sometimes felt as if a bubble, waves, or something was moving inside of me, in different areas of the body (rib cage, legs, chest, arms, legs, face, and top of the head (like when a baby moves inside of a pregnant woman, without the visible bump). My body, head, and neck felt stiff.  Symptoms were milder after 48 hours, on and off, until 4/13/2021 when I felt a sunken feeling, like something dropped inside of me (sugar, blood pressure, blood rush, I do not know). The tense feeling of the body returned. I felt dizzy. Left arm and leg felt tingly. There were palpitations, but I think that it was due to being scared about all the other symptoms. I felt cold and was shivering. The head felt stiff again. I was very thirsty. In the following days, symptoms got milder. On 4/22/2021, at about 4pm, the sunken feeling returned, along with the dizziness, wave or bubble-like sensation through head, face, body. The wave-like sensation flashed across my face, head, and neck intermittently. It was hard to speak, pronounce words, and swallow. The tongue felt numb. It lasted about two hours. I felt exhausted, so I took a nap until 8pm. When I woke up, I felt like nothing had happened, no symptoms until 1:00 am.  At 1:00 pm, 4/23/2021, the sunken feeling, dizziness, palpitations, heavy breathing without shortness of breath, cold/shiver, blurred vision, the wave-like sensation, and pokes suddenly returned. The waves were more intense and felt like pressure on the right side of the head and left side of the chest. Went to the Emergency Room. With every wave of sensations, was accompanied by an urgency to urinate. I urinated like 3 times in a span of 30 to 45 minutes (full bladder). Findings were normal but symptoms continued through 4/24/2021, on and off. Each episode lasts anywhere from 1 to 4 hours.  Short lasting, mild symptoms returned Monday 04/26/2021, at night, until Wednesday 04/27. However, that Wednesday night, I felt a belt like, tight sensation around the left bicep and neck. It felt as if I was being grabbed by the left arm.  On 4/29/2021, around 5:00 pm, I called an ambulance because all symptoms had returned ?full force?, such as sunken feeling, blurred vision, dizziness (like passing out), intense head and left chest pressure (in waves, like having a huge fish or parasite inside the chest and head), numb mouth (like dental anesthesia), hard to speak (hard time sending the message from brain to mouth). It took great effort to speak and felt that I had to decide whether continue speaking or staying conscious. I also had blurred vision with the first sunken feeling. Symptoms continued 2 to 3 times a day. Since 4/29 a feeling of being inside of an elevator, airplane, or earthquake, and the numbness on the left side of chest and arm remain, even when no other symptoms are present. Also, both arms become numb while sleeping, every night, multiple times a night, since 4/29. Since then, I sleep on 3 pillows (two in my head, one on the shoulders to create an angle) to minimize the numbness of the arms and the head/neck pressure while sleeping.   On 5/5/21, symptoms began while car riding as a passenger and upper body felt tight. Strangely, symptoms ended when car stopped moving. Later that day, while walking through a department store, nostrils felt uneven, as if the left nostil were breathing cold air while the right was taking warm air. That night, symptoms intensified (the attack). Like all other times, urinating was too frequent while ?the attack? is present. This time, my body felt sore and tired (Flu-like). There was an intense pressure on the right side of the eye and forehead. The neck stiffness was intense.  For the past two weeks, ?attacks? have been less frequent, about 2 to 3 times a week, lasting a maximum of 2 hours. The numbness on the left side of the chest and arm continues. The feeling of something moving or pins/needles may appear sporadically throughout the day. At times, they feel like twitches. The woozy feeling of being inside of an elevator remains. Breathing still feels heavy, like trying to breathe with the face in front of a fan.  All test results from the 2 ER visits were normal, including the CT scan. A brain MRI, done on 5/5, was also normal. A 24-hour heart monitor also had normal results.
