Apparently I have a BP of 138/98 and a peak flow measurement of 350.
Diagnosis - Asthma so i'm on Serotide 50 to see if i can get it under control. Apparently it could be a combination of dust allergy and/or an allergy to our pet rabbits :( hoping it's the former not the latter.
Anyway, I thought i'd let those of you who helped know the outcome. Thanks for your advice.
