mere bete ko 3 month vaccine diye the 3 din hogye but wo jhga par sweeling aur mota mota lgra hai toh kya karna chahiye

A. You should always keep ice cube or cold pack on the area when you get the vaccination done and apply the tube thermophob that is going to help in reducing the swelling as of now check with the doctor if you need to do hot compress or cold as it has been three days already
