The caller states she seems to be having an adverse reaction in her arm. She states it chronic and wont go away. Caller explains it developed a couple months after she received the COVID vaccine. She has arthritis and she assumed it was just arthritis. She went to the doctor and complained and complained and nothing was done about it. She finally was sent to an orthopedic doctor who did an MRI and based on the MRI, the orthopedic doctor did not think arthritis was the cause of all this pain. She states the pain is not in the shoulder blade itself, but its down about 4 inches from her shoulder, in the area where she received her vaccine. She figured it was just arthritis. It never crossed her mind, this pain could be from the vaccine until yesterday when one of her neighbors made the comment about it and the caller thought maybe it is the vaccine because where she hurts is where the vaccine was administered in her arm. It hurts in that spot and will not stop. She had the MRI done and they were actually thinking she would have a nerve burnt to stop the pain, but her insurance doesnt cover it. She will wake up in the middle of the night whining and crying in pain because she rolls over on that arm. The pain is debilitating. She mentions she has tried everything, she has been to physical therapy.   Follow-up attempts are completed. No further information is expected.
