Hi , my 3 month baby got vaccinated with IPV2 a day back & since then he is crying too much and his right leg (near injection area) is also swollen and also he has fever. I gave him paracetamol syrup for fever but I think his leg is still paining due to which he is continuously crying. I applied some ice also but it didn't seem to work. Please give me some advise or medication to reduce the pain and releive him asap. Also I wanted to know does this vaccination always painful and cause these type of symptoms. Please revert back as soon as possible.
