Clinical narrative: Patient received IIV in her left upper arm around 0830, on 8 Nov 2016. Does not recall anything different about vaccine administration technique. Around 1800 on 8 Nov 2016 (day of vaccine receipt), patient noted a burning pain in her left hand, primarily in palm and fingers. Pain is intense (7-8/10) and constant; It worsens when the affected hand is near heat like when washing hands with hot water or when hand is in contact with laptop; pain has not changed in character over the past 15 hours. There is no numbness and tingling or weakness of extremity. No changes in the appearance of her hand. No history of trauma. Patient went to ER last p.m. (8 Nov 2016) and did not mention receipt of IIV earlier in the day. She was instructed to take BENADRYL to help her sleep, but no additional instruction and no diagnosis. On 9 Nov 2016, patient evaluated. Per PCM: 22 yo F presents to clinic with pain/numbness in her L and R hand and fingers for the past 2 days. SXs started the night after she had a flu shot and she believes that it may be an adverse reaction. Heat is the only thing that triggers the SXs--primarily located in palm and distal finger tips of all fingers except for thumb. She has taken TYLENOL with no improvement in SXs. Denies fever, chills, recent hand/neck trauma, HX of carpal tunnel, HX of reactions to flu vaccinations, neck pain. Does admit to HX of tendonitis in hands/wrist/forearms.
