Strange problem of a sore tailbone when riding recumbents
I've now been riding recumbents for some 12-15 years including many years of commuting on them. Now at 57, I suddenly seem to have developed a sore tailbone and riding a recumbent in the reclining position seems to put pressure on it. Its not excruciating pain but enough (maybe a 4/10) to make me uncomfortable. Has anybody else ever encountered this issue? If yes, what did you do to recover? And how long does it take to recover?
I took a month off but a short test jaunt on my recumbent brought back the pain/soreness. My seat is not really super-reclined. I also don't think this is a case of recumbent butt. I don't get this pain when I sit upright at my desk but I notice some discomfort when I sit on a my recliner chair at home. For both the reclining chair and the recumbent bike, leaning back against something seems to make the tailbone problem worse.
So, I am in this odd position of contemplating switching back to DF bikes as the more comfortable choice, given this tailbone pain. I'm not super-enthusiastic about switching, but if that's the only way I can bike, I will probably do it. Anybody advice or pointers based on your experience with this kind of thing would be appreciated. Thanks.
