So I've been having some back issues over the last two years specific to biking and, more specifically, to climbing. I'll make it brief.

-Been biking for 4 years.
-Back pain began gradually last year.
-Originally attributed to long rides and prone position.
-Play other sports without any back issues at all.

Noticed just this week that it occurs only when climbing. Biked for an hour, 9/10 effort, on flat roads, Tuesday. Not even a twinge.

Just now, biked up a 2 mile hill, ~8-10% avg grade, almost immediate back pain. It's my lower back, btw.

I will say that I was diagnosed with a slightly herniated disk about 2 1/2 years ago but it's so minor, I haven't had it surgically repaired. I mean, I play soccer without any issues at all.

I know the de facto response is to visit a doctor; however, how am I to explain that I have virtually no issues at all EXCEPT when climbing hills on a bike. Unless I miraculously happen across a doctor that knows quite a bit about biking and the kinesiol behind it, I doubt it'll help. I'm just hoping someone on here has had similar issues and can advise.
