Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain Tdap injection is an
immunization injection to fight three fatal diseases Tetanus,
Diphtheria and
whooping cough..
As you have got redness and itching with it many a times mild itching and redness is common due to
allergic reaction as the immunizations contain allergens that can initiate antibody formation in the body that can life long fight with the disease and do not let it flourish..
As you are not relieved with anti allergics ad ice packs there is a possibility that reaction is severe and you may need injectable anti-allergics and
steroids for resolution of symptoms..
You should continue taking anti allergic right now and apply steroid ointment over the rashes and also keep doing cold compresses..
But consult a Physician early and get evaluated..
Hope this informations helps..
Thanks and regards.
