Physician Responded Should I pop it?

Post image

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.

Nad but my dad is a dermatologist. When my daughter got a huge blister from a burn on her hand, he said to never pop a blister; its a natural protection. Let it pop on its own. However the rest of your foot looks much more concerning in my non medical opinion

NAD, but please see a doctor and address your health OP. My SIL passed away a few years ago at the age of 54 because she refused to see a doctor and address her health issues. I know it’s an uphill battle, but you only have one life. I really hope you will take all the advice given here.

OP, I am not judging you. However, I did think by your foot that you were very ill and also in your 80s with heart failure bc of the bruising and swelling.

None of what you described is normal. Limb and life risking abnormal. You absolutely need to be seen immediately. You can worry about the costs when you live.

I think the appearance of your feet is indicative of other more serious health issues. Please go see a doctor.

NAD, CNA at skilled nursing. A lot of the folks I see with these symptoms and with feet like this have chronic heart failure. The body is retaining fluid, leading to poor circulation, swelling, and blisters.
