It's really not something to get too excited about. It's generally controllable. We all deal with something right? Honestly, though it's quite painful when it flares up, in my case at least, it's easy to control. Remove the source of inflamation, treat the inflamation, use caution for a few hours, days, or weeks (depending on how badly I've inflamed it), and go on with life.

Respond to flare-ups immediately with a single maximum dosage of ibuprofen (not an overdosage, just a maximum dosage). This does wonders for taking down the inflamation, which breaks the cycle. Make sure your shoes aren't making it worse. Switching from Specialized Tahoes, which were too narrow, to Sidi Dominator 5 Megas (which are wider) got me to a point where I'm not re-inflaming it. That's important.

It's never kept me off the bike for more than a day.
