When I measured my peak flow last night the actual process gave me quite a sharp pain deep in my chest. I had the same this morning but the pain was more intense and although no longer sharp, I still have a lingering 'soreness' a few hours later.
I've been measuring by peak flow for years and never had anything like this. The only problems I've ever had are breathlessness/coughing/exhaustion when my asthma's been particularly bad.
Has anyone experienced this or have any idea what's causing it? My asthma is pretty poor at the moment and my PFs are low. I'm seeing the doctor next week so I'll mention it then. I really need to be measuring my PFs carefully at the moment so not doing them to avoid the pain isn't an option.
