I have taken first dose of covishield five days back. I had fever for two days! took a crocin and I am ok after that. Little arm pain at the site of injection. But I have a pain at the right side of my neck and head joint cervical. Like muscle pain, difficult in movement. Is it due to the vaccination. What medication can I take. I have just applied volini. And hot fomentation. No relief. Kindly help.
