There's NO REASON to fuss with or replace your saddle. Anyone who is telling you to has probably never really experienced this pain (probably either because they never stop biking, or because they ease in very gradually). This pain is normal, unavoidable, intense, and, believe it or not, very temporary. It happens any time a bone surface is being asked to become load-bearing for the first time (or the first time in a long time). If you only get on the bike once a week to start, you'd probably never have noticed. Go from nothing to every day, you'll be hurting, bad, as the tissues around your bone will be sore and swollen. My husband is going through this right now, too.

It's possible that this pain is more intense than the pain you remember since your riding style (in the saddle all the time, v.s., standing?), terrain (hard surface vs. dirt?), riding frequency (twice a day vs. once a week?), weight, and time away from the bike are possibly factoring in. It's the same kind of pain, though, right?

Within a week or two, your bones will be used to bearing your weight, and it won't be at all painful anymore. You'll know you're on the mend when you think "how can people stand this?" for the first few minutes, then only when you hit a bump, but aren't feeling half bad by the time you arrive at your destination. On the return trip, you'll have the same thoughts, but each day past that point you'll be feeling better. If you're still uncomfortable in a couple weeks, think about frigging with stuff, but I can virtually guarantee you won't need to.

Take a few days off the bike, if you like. It won't matter either way to how quickly this pain goes away, but if there's no need to suffer, sometimes it's best to just keep things fun
