DS tested positive last Saturday - this is day 9. He's not been too bad: he's had aching muscles, headache, sore throat, nasty cough but the worst thing is the breathlessness. After climbing the stairs his heart is racing, his chest is tight, he feels breathless.
How long should it take for these symptoms to go away? He's usually really fit - he's a county runner - so it's horrible seeing him like this. He also has asthma, but his peak flow is currently good (about 450).
