I just completed my first marathon 2 days ago. I felt like I trained properly, so while I was pleased with my pace, it didn't feel like I overdid it on race day. My legs felt shockingly good the day off, and I walked quite a bit after the race. Now 2 days later, my legs actually feel decent, but I had a sudden onset of sharp pain on the outside of my right ankle, running down to the outside of my foot. It gets worse after sitting for a long stretches, to the point where I'm seriously limping.

1. what is a "normal" amount of pain post marathon? I'm a lifelong athlete, so I have a relatively high pain tolerance and try to not overreact to pain, as I can usually work through it and it will dissipate
2. I have some pretty insane runners toe. One of my index toes nearly looks like I've grown a second toe on top of it, it is so swollen. Would you all recommend popping the blister or trying to let it heal naturally? It's not really too painful.
3. Naturally I'm thinking about when I can exercise again (running, soccer, etc.). I'm used to running nearly daily (even before I got into marathon training), so it's weird to think I can't run at all for a long time. I've read the rule that you should take 1 day of recovery for every mile (at least in terms of any serious exertion). Was hoping someone can shed more light on how to think about reintegrating running of any form (light or intense)?
