Additional Information: Additional information: Caller is a consumer who received the first dose of Pfizer Biontech COVID19 vaccine on 18Jun2021 and did not receive his second dose yet. Caller had symptoms on his left leg with electrical impulse wrapped around his leg. It started with his left calf with sore muscle pain that went away then went to his right leg calf with sore muscle pain. Caller went to see a foot doctor and was told to call Pfizer to check if anyone has reported this. Received call from consumer regarding Pfizer COVID vaccine.  He had some adverse events that all happened after first dose. He did not wish to provide an email and did not have an address, phone, or email for primary care provider. He was drowsy after getting it, about 30 minutes after took a nap.  The next day, he felt normal.  He had a headache first day through the night. He slept through that and next day felt normal. Three-4 days afterwards, he started getting almost like sore muscle pain on left calf.  He only felt it when he stood up.  Laying down was fine.  It started 22Jun2021 or 23Jun2021. It stayed same and was persistent and went away about a month after, about 20Jul2021. Then it was weird, because he ended up getting on right leg too and different times where it was still there, but more sporadic and did not last long.  The right leg started 26Jun201 or 27Jun2021. It got a little worse from initial when it started, but then stayed about the same.  To date, he has found ways to manage it.  If he has pants on, it masks and he does not feel it as much.  Every once, he feels the sensation on right leg, but the right leg is more on the right side and maybe to the calf, but more on the shin too.  When wearing shorts, he feels it more.  It is more like when it is exposed. He had a little bit of chest pain that started on left side from below nipple around underneath arm and did not go all the way to the back.  It almost felt like muscle pain.  The chest pain came and went and was not persistent.  After a couple of days, it went away.  Left leg stayed for a few weeks. This chest pain started 22Jun2021 or 23Jun2021, the same time as left leg.  It went away after about a week but was more sporadic and not as persistent as left and right leg.  If he does muscle stretching on his chest, if he works out pecs, it makes it feel better, but it is still there. Every once in a while, he still feels it. He started to get weakness about a week after.  On 26Jun2021, he did yard work where he was lifting patio stone pavers for a couple of hours and right after, he was wiped out.  The next week, he did not have a lot of energy, so he was a little nervous at that point, because he was having different side effects and did some bed rest for the next week.  Then it was back to normal. He mentioned arm pain like when you get flu shot, you get arm pain.  He said he did not have a manufacturer, lot or expiration for a flu shot that caused arm pain. He doesn't know if it is caused by anxiety, but around 24Jun2021 or 25Jun2021, he felt like he was having a large heartbeat. He could feel it more.  He does not know if it is because he had muscle pain as well. The chest pain, there was muscle pain or whatever, he feels like that lasted a while and it is typically when he is laying down in bed at night that he notices it.  He still has it every once in a while.  A few times in the 2-3 weeks after having the shot, it was really persistent and kept him up at night.  During that time, he did go to ER about 3 weeks after and they did EKG and blood work.  There was no sign of heart inflammation or blood clotting.  EKG was normal as well.  It is improving, but still has it every once in a while. Probably 2 weeks after on 02Jul2021, he had left leg when laying down, it happened one time, he had an electrical line that started at thigh almost at butt, and it did a motion where it wrapped around thigh, knee and calf and wrapped around leg.  It was almost like his leg was getting ready to fall asleep.  It lasted 30 seconds and he shook his leg to try and get it to wake up.  He said it went away and had never had it before. When speaking about if the injection was given in the muscle, he stated he barely felt the needle go in. All of his blood work was good.
