Has anyone else had long covid , without a definitive positive test or antibodies ? How did your long covid get diagnosed?
I've been ill for 4 months with what seemed like covid, but tested negative (multiple PCR and LFT). Subsequent bloods show no antibodies. I'm double vaxxed.
Back in Feb 2020 I had a very nasty virus (all covid symptoms except loss of smell) and was ill for about 3 months. No testing available at that time.
I currently have cough, tight and sore chest, exhaustion, dizziness and feeling spaced out, palpitations, very croaky, sore throat. All of these symptoms wax and wane and have been going for 4 months now.
I know it could be another virus and the dr is doing more tests.
It feels never ending. I'm usually a fit, active person and I'm just floored even when doing mundane things. 
Any insights or advice will be much appreciated. Thanks covid hive-mind.
