I’ve been unwell with strep throat recently, very sore throat and swollen tonsils, chills in the day time but night sweats, headache, mucus on chest but no cough. I took a LFT and it had a very thin but dark positive line. Every line since has been the same and doesn’t look like the standard size of positive results. I am on antibiotics for my throat which have helped, but I’m concerned either this is a side affect or Covid or the test is wrong and detecting a different viral infection. Can anyone shed some light on what may be going on please? (I have been isolating regardless and spending Christmas alone)
