I’ve felt absolutely awful for 4 days now, my glands are up, my kidneys ache, I have a permanent headache and it is literal agony to swallow, like I’m swallowing balls of fire every time. It’s keeping me up at night and I’m exhausted (new baby and toddler to look after). I can usually just plough on when I’m poorly but this is another level. Is there something rotten going round atm? Covid tests all negative so far. What is it and how do i get rid of it!
