I am a Medicine Physician.  I had many side effects after the Pfizer Vaccines.  The first Pfizer Vaccine side effects were worse in terms of the number and the severity of the side effects experienced. The main side effects that I am still having trouble with and going to physicians (ENT, Hematologist, and PCP) about are tinnitus, hearing loss, sinus pain and congestion, and headaches.  On 4/24/2021 at about 1:30PM, the initial pain at the injection site upon injection of the first Pfizer vaccine felt like a flu vaccine.  About 1 hour after receiving the first Pfizer injection, my entire face and  neck became flushed.  The flushing was present for 24 hours.  Around 10:00PM on 4/24/2021, I developed a headache radiating to the back of my head and down my neck on the left side.  I also developed severe sharp stabbing left sided sinus pain (felt like an ice pick jammed up into my nose).  This pain had been been under good control with mometasone nasal washes which were started at the end of March 2021.  I also developed left arm pain at the injection site that continued to worsen.  During the night, I had about 3 episodes of brief 10-second-long chill-like cold tingling wave sensations from the tops of both thighs down to my feet (the soles of both my feet felt tingly) and also waves of multiple chill-like cold tingling sensations from the bottom of my rib cage and radiating up toward both shoulders and down to my elbows.    When I awoke at 8:15am on 4/25/2021, my face was still flushed and my entire left arm was so painful that I could not move it.  The sensation felt like it was a painful hematoma in my arm; however, fortunately, the arm showed no signs of hematomano bruising, no palpable hematoma.  Also upon awakening, I continued to have severe sinus pain as well as left sided tooth and left jaw pain.  I had left ear pain. The left ear felt like it was shut.  I was slightly ataxic and felt foggy. At 9:20AM on 4/25/2021, I developed a low roaring or low-pitched harmonica sound in my ears.  I also developed a severe pain in my left eye.  My eyes were watering and "glassy" in appearance.  Symptoms all seemed to be on the left side rather than the right side.  At 10:45AM, I developed severe fatigue and laid down.  While laying down, I had one chill-like cold tingling wave sensations from the tops of both thighs down to my feet and two waves of chill-like cold tingling sensations from the bottom of my rib cage and radiating up toward both shoulders and down to my elbows.  I fell asleep for 3.5 hours.  When I awoke at 2:15PM, it felt like I was getting up after having just been run over by a truck.  My temperature was 99.5F. I continued to have a headache, mainly on the left side, throughout the day.   I also had general malaise, nausea and decreased appetite the entire day.  I was only able to eat 1 ½ bowls of soup, a piece of toast and a cup of hot tea for the entire day.  At 3:45PM, I took Pseudoephedrine 60mg for the severe left sided sinus pain over my left eye and my headache and laid down.  I had two waves of chill-like cold tingling sensations from the bottom of my rib cage and radiating up toward both shoulders and down to my elbows at 5:50 PM.  The persistent left ear and jaw pain were resolved.  The left sinus pain was slightly improved.  The left arm was sore but slightly improved and I could move it around with less pain. I began to experience a general hot sensation over my entire body.  My temperature was 99.6F.  At 9:00PM, I took a shower.  The shower made my arm feel slightly better.  Around 10:00PM, while brushing my teeth, my forehead started to sweat and I again had hot sensations over my body.  My left nose and my left arm were both sore.  I had a difficult time sleeping, I had two episodes of the chill-like cold tingling sensations described above.  I had nausea.  I also awoke in the middle of the night to severe pain in my nose and nasal congestion used Afrin nasal spray.  When I awoke at 8:30AM on 4/26/2021, I had a headache behind both eyes.  My eyes were watering and they were very sensitive to light.  I could barely open my eyes when I awoke because of the pain from the light of the day.  My left arm pain was much improved and fully moveable.  At 10:40AM, I noticed that my inguinal lymph nodes were very painful at the tops of both my thighs and walking was difficult because it made the pain worse.  I also had lower back pain. At the start of the day, in terms of pain intensity: my groin lymph nodes and lower back were having the worst pain followed by the headache behind the eyes/ eye pain/ light sensitivity and then the sinus pain.  I began to wonder if the vaccine was triggering some past symptoms that were suspicious of an immune/rheumatology problem whose symptoms had not been fully figured out.  By 8:10PM, I was feeling that most all the symptoms were slowly improving.  I still had slight left arm pain.  I had a difficult time sleeping.    At 5:00AM on 4/27/2021, I was sweaty, hot and nauseous a couple times.  I took 1 Tums and went back to sleep.  At 5:45 AM, I developed tingling sensations in the right calf for 45 minutes then chill like sensations down my entire leg twice.  I fell back asleep and had bizarre dreams.  I woke up startled because of a loud vacuum cleaner sound along with sounds of pots and pans banging in my ear.  I had ear pain.  I also heard a different mechanical type sound that moved from one side of my head to the other side of my head.  I e-mailed to my hematologist at the Center about my side effects.  I went to the lab to get my routine labs and INR.  At 2:10PM, I developed severe fatigue and slept until 5:30PM.  I had little appetite and ate half my supper.  When I laid down to go to bed, I had vertigo (room spinning sensation) for about 1 minute.  On 4/28/2021, most symptoms were improved or resolved.  On 4/29/2021 at 1:00PM, I noted the painful inguinal groin lymph nodes bilaterally that had returned but not as severe as before.  This time the lymph nodes hurt worse when sitting than standing.  Originally, it hurt worse when standing.   Between 4/30/2021 and the date of my second Pfizer vaccine on 5/15/2021, I continued to experience symptoms of tinnitus and occasional bilateral inguinal lymph node pain, pain in the eye/head from light sensitivity and sinus pain/headache.  On 5/12/2021, I e-mailed my hematologist office at the center about my side effects.
