She normally coughs every day because she has chronic bronchitis and it has been very painful to cough. Around 4 PM, pain in her left armpit gradually got worse and moved to her hand and all of her left arm on 12Apr2021. She also had pain on the side and above her left breast on 12Apr2021. The pain was so severe she went to the ER the night before because she was concerned, she might have been having a heart attack. The ER checked her out and found nothing and she followed up with her primary care doctor and has not gotten a response yet. There was more pain and swelling and redness at the injection site (on 08Apr2021) and it took a little bit longer to resolve but it has resolved. On 11Apr2021, she woke up with a terrible pain in her back under her left shoulder blade and as the day went on it, the pain got worse as the day went on, so she used a heating pad and a handheld vibrating pad for about an hour. She developed a bad pain that came on gradual in her left armpit. She went to bed with the heating pad on her back and yesterday, 12Apr2021, the pain was worse. When she coughed there was extreme pain. She normally coughs up phlegm every day because she has chronic bronchitis and it has been very painful to cough. After a while she could feel the pain in her left hand coming up her left arm. Essentially her whole left arm, left breast and above her left breast. She called the urgent care and called her primary care doctor's after-hours service and spoke to the doctor. She was worried about a heart attack or side effect of the vaccine and the doctor on call advised her to go to urgent care or emergency department for an EKG.  She went to the emergency department around 8:30 PM. It took her an hour to get in a room. The emergency department did an EKG, they took blood and inserted an IV, but they didn't give her medication in the IV. She got a nitro paste patch on her left chest. She also got 3 baby aspirin to chew (a preventative for her heart. Aspirin 81mg Equate brand, low dose chewable), and a chest X-ray. The emergency room didn't see anything. Everything looked good or normal. The emergency room was looking for an elevated troponin which would indicate heart trouble and her troponins were not elevated. While the emergency department nurse was going over this information with her, she had a feeling of indigestion on 12Apr2021, so she was given a GI cocktail. The nurse told her it would numb her mouth and not to eat or drink for 30 minutes. It was a thick liquid. It was to coat her stomach. She doesn't know what was in the medication. Her symptoms are possibly related to the COVID 19 vaccine in her mind because she received her second vaccine on Thursday 08apr2021 and started having these pains on Sunday, 11Apr2021. She doesn't know what else to do. The pain could be from several things and she's concerned. She reports her white blood cell counts are normal for her. Her platelets are slightly high, but they are normally high for her. Her A1C is in range at 4.6%. Her thyroid is normal, her vitamin D is good, and her cholesterol is good except her triglycerides (12Apr2021). Her pain medicine is not touching this pain that she's having.
