Symptom narrative

Patient received a HPV #2 vaccine in office on 5/27/25. Administered in the left deltoid muscle. Mom called our office on 7/10/25 due to a lump that developed under the tissue at the injection site along with a tingling sensation in patient's arm. The lump was sensitive to touch and when palpated, patient would feel a tingling sensation down his arm to his hand. Otherwise, no pain or trouble moving his arm or hand. Upon collecting history, mom states that the lump developed immediately post vaccination on the same day. Mom also confirms that patient experienced mild arm soreness for 1-2 weeks post vaccination. Patient iced the deltoid muscle which improved the arm soreness but did not improve the lump at the injection site or tingling sensation. During the phone discussion with mom, it was recommended for patient to try a warm compress for 10-15min with massage. Instructed to do this twice daily for the next several days. Mother was instructed to make a follow up appointment that following Monday 7/14/25 if there was no improvement. Attempted to follow up with parent on 7/14/25 but unsuccessful; voicemail was left at 11:42am. Successfully able to follow up with mom on 7/18/25. Mom states that patient is doing much better. Explains that the warm compress and massage greatly improved the lump that was at the injection site and the tingling sensation has fully resolved.
