I just completed my 4 rabies vaccine schedule (0,3,7,28)� from government hospital. And they gives rabies shot on my both hand in same time with same syringe and injection is different .they said it - insulin syringe and it's different small needle thin syringe. While I am taking my last rabies shot (4th) on my both hand I didn't feel any pain on both arm while putting injection and no swelling ,no bump, no itching after injection on both arm�.and now I am worried that why there is no pain, no swelling .no bump? Because my previous 3 shot have little sigh of pain ,swelling, bump, after injection on both arm on same time with same syringe 1st shot (felt slight pain, bump, swelling) 2nd shot (no bump on day, and felt slight pain ,but at night I felt� little bump in injection area) 3rd shot (felt slight pain ,bump ,swelling) 4th shot (no pain, no bump, no swelling) now I am worried that is this normal or swelling, bump,pain necessary after injection on both arm?
