While bruised may be too strong, it's pretty normal for an injured or irritated area to be more sensitive for a while. Give it more time to recover, or try to stick to shorter rides for a short while and you should be fine.

There's no need to look further for the moment, because you have the proven "before" history confirming that things were otherwise OK.

BTW - while the butt pain is usually pretty straight forward -- excess pressure or pounding where you sit -- hand pain can be more complex involving nerves and tendons. While waiting to get back to form, you might make a point of moving your hands more as you ride to avoid the "hot spot" as much as possible.
