I had my jab on 29th Jan and my arm is still a little bit sore and a bit hard at the entry site. But getting better each day.There is no place to call and query anything they just say call 111 if you have any problems. There is an online yellow card place to report any side effects but it's long winded. I have had loads of jabs and no way am I still sore after 17 days. It's not overly painful just a bit uncomfortable, i.just wondered if anyone else is experiencing similar.
