Caller states that when she gets her second dose, she had it in the same arm that she received her first dose and reports the next evening she had a "goose egg" under her skin that was swollen, hard, painful to touch, red, and hot. Caller states she just assumed this was normal and did not think anything of it. She reports that over the last 3 weeks this has slowly gotten smaller and report it is the "size of an eraser" that she can feel if she presses on her skin. She states that she has also now noticed that there is a bruise and states that she did not initially have any bruising. Caller would like to know if this bruising is normal with the vaccine as she is concerned since it has been so long since she received her second dose. The patient didn't know who else to call. She had her first Covid shot and waited 3 weeks, then she got the second. She got the second one 3 weeks ago today, and she got it in the same arm. With the second shot she noticed by the next day, it didn't hurt to raise her arm and it didn't hurt until she touched it. She had a swollen area on her arm the size of a goose egg. Over the last 3 weeks it has finally shrunk and is now the size of a grain of rice. Now that it has shrunk, a bruise has appeared. She feels fine. She doesn't have Covid. She smokes, that's why she is coughing. She was wondering if this was something serious. It has been 3 weeks and she still has a bruise. Caller declines to provide a physician. She has not been to a doctor in years. She can't tell the last time she went to a doctor. The patient noticed the swelling the next day on 14Apr2021. She can still feel a little knot maybe the size of an end of a pencil. It has slowly gotten smaller over the last 3 weeks. It was the size of a goose egg, bigger than a regular chicken egg. She assumed it was because she had both shots in the same arm. She should have had it in her other arm. It would have been in the evening maybe around 2200 or 2300 at night because she was just about to go to bed. The lights were out in the living room and she came charging out of her bedroom and caught her arm on the door. She thought oh that hurts and put her hand over it and noticed a goose bump. The outcome of the event bruise was not recovered, swelling was recovering, and she had a "goose egg" under her skin that was swollen, hard, painful to touch, red, and hot were unknown.
