On 21JUN2021, I was vaccinated with Johnson and Johnson vaccination.    On or about August 04, 2021 I exhibited signs of rapid heart rate a pain in my chest. It felt as though there was a sack bouncing in my chest, proximal to my heart, when I ran. This was an uncomfortable pain. I visited Health Services. My blood pressure was abnormally high. A chest X-ray was taken as well. No evidence of myocarditis was present according to the health professionals although I feel differently.   On 12AUG2021, I departed. I arrived and was required to depart the airport and stay at a local hotel, close to the airport.  Later that evening, I returned to the airport and continued onward with travel to my home of record with stops and a final stop on 13AUG2021.   During the initial weeks at home, I displayed no signs or symptoms of having any illness of viruses. On or about 27AUG2021 I began displaying some minor coughing and drainage but did not corelate this to being sick or beginning to become sick nor did I feel these symptoms warranted a further examination by medical professionals regarding possible COVID infection.  These symptoms persisted and worsened overnight between 06 and 07 September 2021.  With this sudden onset of illness, I felt that perhaps his condition was COVID related, and elected to self-medicate as there was only a low-grade fever and minor body aches.  After an approximate week, 14SEP2021, I chose to visit a medical facility for a diagnosis and seek medication to treat symptoms.  I was ultimately diagnosed as being positive for COVID-19 and was given medication, a Z-Pack (antibiotic), and discharged back to my residence. My wife and two sons accompanied me as they all were feeling under the weather. My two sons have no COVID vaccination, and my wife only had one dose of the Pfizer.  All four of us tested positive for COVID-19. My wife, nor my two sons never actually got sick, became feverish or exhibited any harsh symptoms typically accompanied with COVID-19. My daughter, who resides with us as well, never contracted COVID-19 or is vaccinated.    I realized the COVID had become more severe when cyanosis was observed on 20SEP2021 by my spouse. Because of this alarming sign I elected to visit a medical facility, again. I was promptly admitted to the hospital, via Emergency Room, after being diagnosed with COVID-pneumonia and had an Oxygen saturation in the low 80 percentile. The prolonged deficiency in oxygen will play an important part in my recovery as outlined later.     I was isolated on a COVID floor of the hospital and given oxygen via cannular only. Against my wishes I was given three doses of VEKLURY for COVID / Pneumonia as there were no other options permitted by the medical staff at the Hospital. I was discharged from the hospital on 24SEP2021, being allowed to continue to recover at home with a prescribed oxygen machine. My oxygen levels were still in the low 90 percentile, and I had not completely recovered from pneumonia. During the hospital visit, I did not readily associate my troubles sleeping or mental state as being negatively impacted by PTSD. My mental acuity was affected by long-term hypemic-hypoxia at this point but only informed of this information in December 2021, during a medical visit at the clinic.   While continuing recovery at home, I recognized, on or about 26SEP2021, my feet were numb and associated that this condition was due to a week-length stay in the hospital as well as post recovery issues from COVID and pneumonia.  I became concerned when the numbness began to move up my legs and into the pelvic region. It should be noted that once home I suffered from a post-COVID diminishment of my mental faculties (foggy head) as well as frequent fatigue. The diminished mental capacity affected my word recall during speech, memory, fine motor skills, etc. This ?brain-fog? was described by Neurologist at the clinic as not particularly caused by COVID. This issue was me remaining affected by the effects of hypoxia for nearly two weeks in September 2021.    As before, I attributed my current issues as post COVID / Pneumonia recovery but began to conduct some research. By 30SEP2021 my conditioned worsened to the point I could barely walk due to an inability to maintain balance. I returned and was admitted to the Hospital for testing based on these current conditions.   While in the hospital, I was under care of a Neurologist and a battery of tests were conducted.  In the end, no definitive diagnosis was provided by the neurologist, and I was discharged on 01OCT2021.  However, my condition of being unable to walk normally was not altered, fixed, or reversed. In simple terms, I was informed my symptoms should decrease and get better over time although no specified or length of time was given. Only later would Guillain-Barre syndrome be identified as the cause for my medical problems.    On 06OCT2021 I conducted a follow-up exam with my Primary Care Physician (PCP). The PCP espoused the same information as the Neurologist that the ability to fully walk and run would return over time. My pneumonia was in recovery, but two lower lobes were still showing signs of damage.  I was assigned a follow-up appointment with the PCP on 06JAN2022. This follow-up appointment was subsequently changed to 15DEC2021 due to me suddenly being affected by high blood pressure.   The Clinic visit was uneventful on 01DEC2021. Test were conducted and a meeting with the neurologist was completed. The total duration of the visit was less than eight hours. However, it was divulged by the neurologist that most likely the condition affecting me was the result of Guillain-Barre syndrome. The current issues are post syndrome effects and the body is recovering. As well, the neurologist also stated the ?brain-fog? issue was caused by the prolonged issue and non-treatment of hypemic-hypoxia. This as well would take time for the brain to recover.  After returning, I began to experience issues pertaining to my heart. On 15DEC21 I made an emergency appointment with my PCP. It was discovered that I was suffering from Stage-2 hypertension. The cause for this remained a mystery as I was conducting physical exercise daily and monitoring my food quality and quantity.  Post COVID lingering issues might possibly explain the cause. I was prescribed medication by the PCP designed to reduce and control my blood pressure.
