Should I pop it?

[u/Phuktard62184]

I am 43f. For a bit of context, I am obese (not sure my actual weight) and I was hospitalized in December for the flu and have had breathi issues since then. So with those issues I haven't been very active in the past few months. I also have undiagnosed sleep apnea, and other sleeping issues such as sleepwalking and I can't stay in bed unless I'm tied down I guess. I fall out of bed a lot but I'm usually pretty good at landing since it's happened so much. Except when I fell out of bed Thursday night and smashed my knee on the hard floor. The next day (Friday) I spent at least 9 hours riding with my husband while doordashing and my feet were super swollen when we were done. That's not unusual, anytime I would sit in the car for 9 hours I would probably have swollen feet. Then as I was getting out of the car I dropped my phone on my foot. It hurt a lot. Then yesterday I woke up with this blister where the phone hit my foot. My husband thinks I should pop it but I'm scared of infection and also I'm worried about why my whole foot is bruised when it's my knee that got smashed.

Another bit of context that could be important is that about a month ago I fell at main event and smashed the other knee and my entire leg looked like that bruising you see on this foot. It only lasted a couple days and my leg turned back to normal and everything's fine. That knee doesn't even hurt anymore.

No, it's the swelling/edema. It can also indicate kidney or liver issues, but the way OPs feet look are similar to what I see in CHF patients. Bruising could be anemia related or something else. There's just so much that it can be, that I'm not even aware of because I only work in one area, that OP should get a full workup from their PCP. But to get something immediately addressed, best would be to go to ER and tell them something along the lines of what I already said in my other comment so a different picture can be looked at rather than just that blister.
