Patient reported that she had vaccine on Friday and she experienced right in the middle of sternum at the sternum side and pain was transferred to right and left shoulder area yesterday afternoon at 15.00, after throwing a ball to her pet dog for 10-15 minutes with her right hand. After playing, she felt really tired and thought that it was maybe because of the weather but the pain never went away. Primarily stained on the left deltoid upper side, and it was severe if she had rough movement but it was not as bad if she was caseous to not to move too fast or raise her hand. She developed a very sharp pain on her sternum, which radiated from her right shoulder to the left. The pain increased and radiated to her left deltoid where she got injected. She had the pain yesterday afternoon about 15.00 but she suffered of osteoarthritis, and she did not like to take the medication, she would like to keep the pain. But it got worst time went by from 3 to 4, 5 o clock to bed, in bed the pain was bothering severely and the patient took TYLENOL that usually she took for arthritis, 650 mg only took 1. But she went to bed, pain persisted that she could not get up, at midnight it got bad and she had some pain medications because she already suffered from arthritis. And even to swallow it bothered her too. So, the patient took a Gabapentin for osteoskeletal problems and she was sitting here in the kitchen doing some paperwork because the pain was bothering her which she felt that probably the Gabapentin did not help her as usually it does. So, she just wanted to know what type of medication should she take just to minimize the pain. As of calling, she still had pain and mentioned that it was painful just holding the phone to her left ear. She could also feel that it was a little tight in her chest. She mentioned that she has bone pain because of arthritis. She was calling to report this and asked for any advice regarding this because none of her pain medications work and she did not want to mess up her vaccine. The patient reported that when she took Gabapentin and Tylenol as a treatment to subside pain but the pain came back and the consumer wanted to know what she can take, consumer stated. The outcome of the events was unknown.   No follow-up attempts are possible. No further information is expected.
