Foot painful and swollen because of old injury?

[JustLuca 5]

I broke my right foot in 2012. The fracture was right at the top near my big toe. Since it healed, I have very rarely had any pain in that area.

Today I took my dog for a pretty long walk and I noticed that I was starting to have a little bit of pain again. It wasn't too severe so I ignored it. A few hours later I noticed that my foot was in a lot more pain and was swollen and a little bit bruised. I had not exercised at all or really moved during that period of time, I was just sitting on the couch drawing. I'm freaking out because I have no idea what caused it.

I'm a drummer so I use my right foot a lot, I'm wondering if maybe playing the drums a lot has aggravated my old injury or if it's from walking more? I've been doing a lot more of both of those things since the quarantine started about a month ago.

I'm kind of scared because I don't know what happened and I really want to avoid a trip to the ER. Does anyone have any idea what this could be from??

It's definitely still swollen and painful today, I was considering putting ice on it or just wrapping it... Another theory I thought of this morning though was that yesterday I was wearing very old sneakers. They're Vans (which are not exactly known for having a lot of grip or arch support) and they're pretty worn out. I wonder if maybe my foot got strained from wearing shoes that don't have a lot of support or traction. 

Sigh. I don't know. This has got me really stressed out because I'm worrying that I did something to aggravate the old fracture and I'm worried that I'm going to break my foot again and end up in the ER. I'm also worried that it could be something worse than a fracture, like a bone tumor.

I also need to keep taking care of my dog and I would be pretty depressed if I couldn't play the drums for a while. I know the responsible thing to do would be to stay off of my foot until it feels better but I also don't like being stuck indoors and it's supposed to be about 60 degrees out for the next few days. My family won't walk my dog for me and it would also be kind of unfair to ask.

I've broken a lot of bones from sports injuries and never experienced anything like the pain coming back and causing bruising and swelling years later.

Does anyone know what I can do about this, or what may have caused it? I'm starting to worry that it's something really bad.
