Good evening doctor. Hope you are doing well and safe. My mother aged 61 is diabetic and has diabetic related
kidney issues. She had been injected COVISHIELD vaccine on 25th June 2021. Since then she's been having hyper acidity and naseau. After the vaccination she didn't have any fever, throat pain, chills etc. Before vomiting she coughs. Is it beacuse of hyper acidity or something else ? Thank you
