My father had accident today while driving in a sand road. He fell down and we took him to a hospital ( he had fracture and swelling in his right foot and right hand. ) He took his covishield second dose on Tuesday (13th July). He's diabetic but his sugar levels are in check right now. Doctors advised him not to take any pain killers / injections and to take just paracetamol (dolo). He has severe pain. Is it advisable to take pain killers post vaccination? Please suggest.
