The adverse reaction to the Pfizer vaccine started 22Sep2021. I woke at about 4am unable to move my entire body. All voluntary muscles seemed to have been partially paralyzed and I lost (I would estimate) about 90% mobility and strength. I could not bring my legs to my chest while lying in bed, I could not sit up and it was extremely difficult to even move my arms or shoulders in the attempts to move the sheets off my body. I was able to stand with the help of my wife but could not lift my feet more than an inch or so off the floor. She had to help me dress myself as I could not do it. I could only shuffle step my feet to walk. To get in and out of a vehicle, I had to have help and have my legs lifted into the car. After going to the ER, I was seen right away and given test after test. EKG, blood tests and panels, chest x-rays, CT scans of my brain, C-spine and thoracic spine. No definitive answers were found other than things related to my age and military career. It was thought at the time it may have been a reaction to "SOMA" a muscle relaxer I had taken at night starting a couple days prior. The doctors also confirmed that this type of reaction to a muscle relaxer was highly improbable, especially since I had taken it two previous nights with no issues. I was eventually sent home with no answers other than to stop the Soma medication, the reaction did subside in about 24-36 hours (fully). Two days later, (not taking Soma) I was back at the ER where I had been seen previously. Another paralysis episode was underway but not as severe. The loss of strength and function was (again estimating) 50-60%. Although not as severe this time, it was accompanied by short, labored breathing. It felt as if I had sprinted 300 meters and could not catch my breath no matter if I was sitting and resting. Walking only made everything worse. My O2 levels were "normal" when measured. I was observed and more blood panels were taken, tests done, etc. I was sent home later with no answers. To this day, I have not had any more severe reactions to this measure, but almost daily for the past 3 months I would wake up with some muscle group, typically in my legs and arms, not working at full strength or capacity. The muscle groups are normally the quads, hamstrings, biceps and triceps. The feeling is of marked weakness and the feeling of "tearing" muscle fibers when doing day to day activities or work tasks. I work on aircraft and climb up and down ladders or on the aircraft itself throughout the day. I have sought more answers through my doctor but have just been diagnosed with DOE ?dyspnea on exertion & Primary Viral myositis. Seeking answers on my own, I have actually stopped taking my blood pressure medication in an attempt to "troubleshoot" myself after reading the side effects of MICARDIS. The reactions have lessened but I am still experiencing the marked effects from what I can only surmise as being from the Cov-19 Pfizer vaccine due to the timing and effect this is all relative to. I am an active, in-shape 41 year old male who worked out on a regular basis. Eats healthfully and stays healthy, active and energized. After this reaction/vaccine, I am drained daily even after a full nights sleep. I feel incredibly weak and cannot work out on a regular basis any longer due to the, sometimes daily, muscular group fatigue and overall marked decline of my well-being.
