Hello, On 13th April 2021 my father got the first shot Covishield vaccine. For 5 days he was really sick and weak so we decided to get his regular blood test for creatinine and other tests on 19th April 2021. In the results it’s shown that his creatinine level has increased from 3.1 to 3.75. Blood urea also increased to 60. Sugar (110) & BP (140 75) is controlled. His RBC & Haemoglobin count has also decreased. It’s been 11 days since he got the first shot of vaccination and the weakness is still there.. body pain.. mild fever. Doesn’t feel like eating anything. Questions : 1) Diabetes BP medicine to continue? 2) What medicine/food to take to improve immunity. 3) What food to avoid? 4) Paracetamol quantity in a day? 5) Is it safe to take the second shot of vaccine? Kindly help!
