feeling of electrical current going through both hands; slight light-headedness; arm soreness; her cholesterol was a little elevated; This is a spontaneous report received from a contactable female consumer. A 54-years-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Batch/Lot Number: EP6955; Expiration Date: 20Jun2021), via an unspecified route of administration, in Arm Left on 21Mar2021 12:30 as 1ST DOSE, SINGLE DOSE, and second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Batch/Lot Number: EW0153; Expiration Date: 20Jul2021) via an unspecified route of administration, in Arm Left on 11Apr2021 12:30 as 2ND DOSE, SINGLE DOSE for covid-19 immunisation. The patient medical history and concomitant medications were not reported. The patient underwent lab tests and procedures which included patient had a lipid panel and recently her cholesterol was a little elevated and had gone down. The following day of both vaccines the patient experienced a feeling of electrical current going through both hands when using devices such as her cellphone 2 to 3 days after Covid 19 vaccine. The feeling has become mild at this time. Patient had been double vaccinated. She thought the second shot was back on 11Apr2021 or something, it has been a while. She had a very strange thing going on. She had not heard anyone else talking about this as a side effect. Did not know if it was unrelated or coincidental that it started when she got the vaccine. Patient inquired if anyone has reported anything about side effects while holding electronics. When holding an iPhone or computer touch pad, she feels almost like an electrical current going through her hands. It was a very strange feeling. She was not a conspiracy theorist at all. When this first started, she called Apple because she thought it was a problem with the phone, like something was emitting something or something was wrong with it. They checked her phone, and everything was fine. She had been to a hand surgeon, hand doctor who thought it may be carpal tunnel. It started right after the vaccine, about a week and a half after she got it. When she holds her phone or computer, on the track pad, it felt almost like an electrical current, like when you get shocked, but just like a mild thing, coming through her fingers into her hand. It was a very strange uncomfortable feeling. About a week and a half after the first vaccine it got so bad, she could not even hold her phone for like two days. She had to carry around holding her shirt out and dropping it into her pocket to hold it walking from room to room. It had been hovering at a low level where she could hold the phone in her hand, but for a couple of days, she could not even hold it. About five days after her second vaccine the same thing happened again, where it was about two days worth of not being able to hold her phone and then it went back to just this very low level and now it had just been staying there ever since then, so it has been weeks and weeks. She was just trying to figure it out. Someone suggested she just call Pfizer and see if anyone else reported anything like this before. The hand doctor treated it as though it was carpal tunnel and gave her a cortisone shot but that did not seem do anything. He thought he would send her to a neurologist, but she thought she would call Pfizer first. Monday, that she finally decided to call Apple. She did not know exactly what day it started, if it was a day or two days afterward but it had been going on about a week when she decided to call Apple. Her husband was holding her phone and he could not feel anything so she held his phone and she could feel it on his phone too and it was really weird. She could even feel it when she put the phone down. Feels it a little bit right now, it did not go away right away. Its kind of has been up and down a little bit. Right now, it was kind of settled. For several weeks it has settled at the same level. It was fine, she could hold the phone, it was just not that comfortable. She had to switch hands, the longer she was holding it, the more it bothers her, and she needs to switch hands. About 10 days after the first shot, it got so bad she could not hold her phone for like 2 or 3 days. Lets see what happens after the second shot. At that point, she had already been to the hand surgeon and he said the same thing, let just see. He thought it might be carpal tunnel and it might have just been brewing under the surface. It could almost be like another side effect that could have brought out the carpal tunnel. The only other side effects from the vaccine were arm soreness It was afterward, and was very brief, until the next day. It was subsiding when she got up in the morning, then went away. and slight light-headedness for 15 minutes. It was a brief time after, maybe an hour. Occurred after both the first and second dose. The doctor gave her the cortisone shot in one hand, so she could compare. She still has it in both hands and has been about 2 weeks since she had the Cortisone shot. She has a follow up appointment with him this afternoon so well see what he says. She just wanted to report this to Pfizer first before she saw him to see if Pfizer had any information. She stated she hopes she is not going crazy but it is a weird thing. Anyway, it was about 10 days after the first shot, it was so bad, she couldn't handle the phone and then 5 days after the second shot. Each time, it lasted 2 or 3 days and then was back to the way it was again. It only got really bad twice, after a shot, then after another shot. It could all be coincidental and something else is going on with her but she wanted to see if anyone else had reported anything like this. Took some Tylenol after the first shot, after the second, didnt take anything for other events. The outcome of the events was unknown.  Follow-up(09Jun2021): This is a spontaneous report received from a contactable female consumer. New events were added. Follow-up attempts are needed. Further information is expected.
