Hi...My husband and I took the first dose of covishield on 4th of this month. After 7/8 hours my husband felt sick. He was feeling weak and then after going to bed at night he got high fever and headache. Next day fever was 101 plus headache and he took a paracetamol to ease things. Now after 4 days there is no fever, but still feeling weak, have mild headache BUT HAVING FEVER BLISTERS and SKIN INSIDE MOUTH IS PEELING. This is a bit concerning for us. Kindly suggest if this is unusual and need to visit a doctor. Strange that I did not feel a thing after vaccination like him. He took 3 tabs of Paracetamol- Calpol 650.
