Sore arm after my initial vaccination in my left arm; This is a spontaneous report received from a contactable reporter (Consumer or other non HCP). The reporter is the patient.  A 73 year-old female patient received bnt162b2 (BNT162B2), administered in arm left, administration date 28Jan2021 15:30 (Lot number: EL9261, Expiration Date: May2021) at the age of 73 years as dose 1, single for covid-19 immunisation. The patient had no relevant medical history. The patient's concomitant medications were not reported. The following information was reported: PAIN IN EXTREMITY (non-serious) with onset 28Jan2021, outcome "recovered" (20Feb2021), described as "Sore arm after my initial vaccination in my left arm". Therapeutic measures were not taken as a result of pain in extremity.  Additional information: It was reported that the patient had her second one on 18Feb2021 it was given in her left arm. For the next three days the patient's Right arm experienced an old injury which was quite painful. When she experience this injury years ago she saw an orthopedic surgeon and with exercise the pain went away. This time, the pain just disappeared on the third day. Then about two weeks later the patient had a vertigo experience. She had experienced vertigo over her lifetime so she had anti vert. About three days later she felt better, able to get out of bed. But the lingering dizziness remained when she tried to sleep on her left side. Two weeks later it happened again, much more violent with vomiting. The effects lasted. Then the foggy brain began and the double vision, eyes painfully burning. So tired that she could not stay awake. Due to the vertigo, the patient saw an ENT but nothing came of that she also experienced neck pain that was quite debilitating. The patient sought PT. Her double vision was unusual as she wore prism glasses which had fixed that issue in the past 4 years. Her dry eye caused her issues but now her eyes were so painful that she had to rest several times a day, needed to use drops a lot and an optase mask daily. The foggy headedness was terrible. The patient still had issues finding where she left things during that period of confusion. About May, the patient noticed some subtle changes. She was not sleeping so much, sometimes her eyes felt fine and she was really getting her life back. It would last 5 to 10 days and she would be back in the foggy headedness, sleepiness and burning eyes. Her neck would get really stiff leaving her once again tired. The patient went to an ophthalmologist and a retinologist as she did have macular degeneration. The ophthalmologist sent her to an optoneurologist based on her many complaints. The patient was diagnosed with a lazy eye in fifth grade. After many hours of tests at the neurologist, she agreed that the double vision was probably from the lazy eye but she wanted an MRI. She went for an open MRI. Although the results were good the main issues of the optic nerve were not seen clearly. They wanted her to have another but she did not do that. The neurologist sent her to an opthortist at one institution. Her eyes had gone from a 7 prism to a 9. A patch was put on her glasses. She got better, felt great and was OK, lots of energy and sleeping less, no drops for the eyes, there was double vision only when she did not have her glasses on. Then she had a bridge in her mouth fail. She needed implants to repair the damage. After the implant surgery on 10Jan2022, the pain in her eyes and the double vision returned. There was not foggy headed, but she was sleeping more, was taking long naps, was using eye drops again and the optase mask. She was not doing the activities, she was doing or was staying up late. She had to rest during the day and had to go to bed early. Her neck had been ok. She also mentioned that everything that was affected by the Covid 19 vaccination had been a problem in the past except for the foggy head and extreme tiredness, the shoulder, the neck, the vertigo, the eyes but the foggy head and extreme tiredness was new to her body. It was like the vaccine was attacking all of her body weaknesses and was causing a few others. Many of the issues that came back were resolved 15 to 30 years before one had the vaccine. She wondered whether or not all of the novocaine (or whatever they gave to numb her before surgery in her mouth) had something in it again that was in the vaccine or something she had a high sensitivity for. It was curious, it took a few days after the Implant was placed before her eyes got worse and the tiredness started. But it was back. Some days were better than others. She was not foggy headed and her neck was not stuck, but the eyes and the tiredness were back. She was hoping it would get disappear. During the aftermath of the vaccine, another problem was looking at the computer screen. She bought blue light blockers. They didn't help. When she felt better in Nov and Dec, she didn't have any problems with the screen. Her eyes were not sensitive to light and vision was great. All of this was a mystery to the patient. She was hoping to be well soon and she knew it was possible for this to go away.  No follow-up attempts are possible. No further information is expected.
