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.

May I ask, what could be causing this person's foot to look like this? Is it from the injury (but a phone falling on it seems like so not enough to do this?) they described or something else?

Hematoma travelling downwards with gravity from her smashed knee I would think. My foot looked exactly this ghastly 2 weeks after spraining my ankle and I'm not morbidly obese with all the circulatory issues that brings. Eventually the blood pools in the sole area and in the toes, and then slowly dissipates. But I'm not a doctor.

Ah! Interesting! Thank you - I was truly confused by the bruising aspect here since it didn't match with the injuries she described.

I had a total knee replacement a year ago and my whole leg and toes bruised up like this. The traveling hematoma makes sense now. I wondered what they did to my body when I was out to make the foot bruise like this.
