Jen, we have been an odd household with symptoms.
Two teens and my husband and I. Son has only felt a little unwell for a day. My daughter has had a high fever and headache, followed by fatigue for days. Me, nearly a fever, odds pains and then a really sore stomach and nausea for a few days.
I have been terrified for my husband as he has two bouts of pneumonia and swine flu in 2009! No idea why he has had this, all in his early 40s. He started 10 days ago and has suffered the following symptoms:
High Fever
Headache
Sharp pain in kidneys
Sharp pain in eyes
Chills and aches everywhere
Exhaustion and
No sense of taste or smell
The last one started 4 days ago, so for him, on day 6 since he started with fevers etc. He is still suffering from this.
However, with many firgers crossed, no cough or difficulty in breathing at any time.
I certainly think we have all had it here. However, as you mention, without testing for it you cannot confirm you have. Hopefully in the weeks to come, testing will become wider ranging once they have got the front line people tested and the whole testing system under control. With your asthama and cough, it is hard for you to know what is best without confirmation. Erring on caution is what you seem to doing which is a good plan.
