Hard lumps appearing after the Pentavalent vaccine can be warmed up with a towel, and if combined with an infection can be treated with anti-infective therapy under the guidance of a doctor.
Pentavalent vaccine is a set of five viral antigenic components in one vaccine, after vaccination with Pentavalent vaccine, if the body appears hard lumps or hard nodules, it may be due to an adverse reaction to the vaccination or caused by infection.
If it is an adverse reaction to vaccination, it is generally mild and can be relieved after a period of time, using a towel to apply hot compresses to the area can promote blood circulation, which in turn promotes the absorption of the medicine, and can promote the subsidence of the hard lumps.
If the redness and swelling of the hard lumps lasts for a long time, and the redness and swelling expand, or symptoms such as pus, pain and fluctuating sensation appear, it is considered to be caused by infection, and it is necessary to disinfect the area under the guidance of the doctor and take antibiotics, such as amoxicillin, for anti-infective treatment.
Do not rub the hardened area, which may lead to aggravation of the symptoms.
