I'm on day 7 and still testing positive on LFT. I'm mid fifties and triple vacc'd. I have had symptoms of heavy cold but improving last two days to the point I could walk in the garden yesterday for half an hour today twice that. However I wonder if I've overdone it as I feel extremely done in and have developed a cracking headache that's resistant to pain relief and feeling more snotty suddenly. Is this possible after 7 days?! I thought for the vaccinated it was short lived and relatively mild. Interested to hear anyone else who thought they were improving then felt worse.
