One of the things about having chronic health problems is that it's remarkably easy to overlook that you're going down with something. For a couple of days now I've had symptoms, but have put them down to other things. Sneezy & itchy eyes? Allergies. Achy limbs? Entirely normal for me. Wheezy? Photochemical ozone pollution. Dizzy and headachy? Travel sickness owing to being tired. Excessively tired for no apparent reason? Just a severe shortage of spoons. Falling-over dizziness attack? My vestibular system crapping out because of lack of spoons. Nausea? Got to be the evil gall bladder again. Thus I don't notice the damn infection until some smyptom turns up that is not within the realms of "normal for me" - that being, a severe sore throat. Even then, I ignored it last night because it felt like the oral thrush I can get from not gargling properly after taking my inhalers :/
Blah.
