Hi all, I have my fourth COVID jab next week due to medical conditions, I had COVID once about 18 months ago and luckily all I had was a horrendous headache for about four days. A few days ago I developed a headache and it is searing and not being touched by painkillers, I also feel knackered and have been falling asleep really early for a few nights and then this morning I've got up and had stomach cramps and the shits (sorry for the tmi and phrasing). Is it worth getting a test do you think? I'm a bit worried about having the Jab if I actually have COVID again at the moment, but have no tests left over from last year. Thanks all :)
