Coccyx (Tailbone) Pain?

Blueberry2012-03-28 13:13:10 +0000 #1
So this is a new one on me - and I'm curious if anyone has had a similar experience....

I started doing a ride everyday challenge in December, and have continued into January (subbing some other activities in Jan). This is much more time than I have ever spent on a bike trainer (and more than I have spent on a bike in a very long time). Normal saddle issues are fine (i.e., little chafing, no sit bone pain). However - my tailbone hurts. Seriously hurts. There is nothing else this could be. The only thing I can think of is that I'm sitting up on the trainer in a way I never do on the road - and when I do, I'm bruising it?

There's only ever minor discomfort on the trainer (and only while sitting up), but afterwards, the pain can be quite sharp. As I'm sitting here, if I squeeze my gluteal muscles hard, I feel some discomfort.

Is this something that goes away? I'm sure I should train myself to sit up less - but being on the trainer is still boring and moving around usually feels good. I don't think it warrants a doctor visit or a bike fit visit - it's just....odd.

I agree with what Knottedyet said in the thread link. It's likely that the saddle is too narrow and on the trainer you don't move around enough to release the pressure or that the saddle has broken down.

I hope that helps.

I don't think it's saddle breakdown - it's the same model I've ridden for 12 years, and a fairly new one in terms of age (not the newest of mine, but probably ~800 miles or less). It's a Terry Butterfly. I suppose it could be too narrow but I'm really, really surprised this would be the first I've seen of it. I've done road rides of 80+ miles (and the training for them) without discomfort on this model.

My theory was that it's the extended periods of sitting completely upright (which would rotate the pelvis backwards in a way that doesn't happen on the road) - as opposed to my normal angle. I'm inclined to play it by ear and see what happens - I hate to start from scratch saddle shopping when these have worked for so long.
