The painful symptoms in the arm after cervical cancer vaccination are mostly caused by the stimulating effect of drugs on local tissues, which is a physiological reaction. For this situation: 1. Patients should pay attention to proper rest, do not perform heavy physical labor or carry heavy objects, and the pain will disappear naturally after 3-7 days. 2. Don’t take a bath within one week, and don’t get wet, scratch or rub the needle hole locally. 3. Pay attention to observe the injection site, if there is obvious redness and swelling and abnormal discharge, it is mostly considered to be caused by infection of the injection site, and appropriate anti-inflammatory and symptomatic treatment is needed. 4. If the pain is severe and affects the activities of the upper limbs, but there is no obvious local redness, swelling or abnormal discharge, consider using hot compresses to relieve the pain, and regularly review the HPV and cervical fluid-based cell examination.
