Hi I am not looking med advice, yet! Don't know how that is viewed on this site. over the past few months i have been suffering from a mild but acute chest pain,when i sneeze and sometimes stretch, which i think and the doc, is down to muscular pain. This came to a head a few weeks a go i did a 4 hour mtb over the purbecks with some guys i used to ride with. i was hanging despite a few months now of riding and no ability to change pace which was something i had noticed during my rides, the guys said when i used to ride with them i was quick and had good recovery, i know i am not where i was then. So i went to the docs a week ago have had plenty of bloods including a fasting glucose test, my god that almost killed me and a chest xray all good fun, lovely bruises on the inside of my elbows, plus the near fainting!! well bloods back all clear! chest xray all clear, nice big lungs, good veins, excellent dissolved O2, well what can i say, excellent peak flow too I managed to get a run in this morning before going to the doc and i was wheezy and struggling i would say due to having done nothing for 3 weeks due to this niggling chest. he had a listen and could hear a few thing so he thinks it may be exercise induced asthma. the asthma nurse came and we all agreed its likely. so now i have to compete a 3 week diary of peak flow before during and after exercise. my question to the esteemed audience, are there any sufferers out there too, i really want to get back into competitive cycling and maybe triathlon and i'm a little concerned that this maybe a hindrance to me. sorry its so long but wanted to get in as much detail as possible.
