The day after her vaccine, she experienced muscle aches, fever and "ran the whole gamut of side effects". What most concerned her was the development of "Covid-arm", which she described as a huge area of redness around the injection site, with a rash and intense heat, and a lump under the injection site and swelling. Two weeks post-vaccination, she was still left with a "little lump", and feared it might be infected. Her physician was unable to see her until the following week. Patient had a history of small fiber neuropathy, and described the feeling in the vaccinated arm as a "restless arm syndrome", almost like restless leg syndrome, which comes and goes. She felt the neuropathy "most in the shot area" and it sometimes went throughout her arm. She planned to go to a local Urgent Care facility as she did not want to wait a week to see her physician.
