Hi cycling friends. I am new to the forum so hi all.I have been cycling now for around 4 years i have a scott cr1 carbon road bike. Over the past months when i ride i have developed a pain around my mid back which seems to be at the back of my rib cage it can last for a few days if i rest up it does go but dont want to give cycling up 2 hour rides i am in a bit of pain.i have had a proffesional bike fit and they say i am set up perfect .i was riding on a 100 mm stem which i felt i was stretching to far forward so i have gone down to a 90mm but i still seem to be gettin this back pain i know its bike related but its really annoying why its happening i m being treated at the physio at the moment they say there dosnt seem to be a problem and have given me stretches to do but dont seem to be budging .I wondered if anybody else had had anything like this, any help will be greatly appreciated
