Swelling in my foot and left palm—any ideas?

It all kicked off about ten days ago with this weird allergy breaking out between my fingers and across my palms, looking like these big mosquito bites that just wouldn't stop itching. It cleared up after a few days, but then it migrated straight to the soles of my feet, so I just used some Benadryl cream and that seemed to do the trick.

Now my feet are swelling up starting from the ankles, and my left hand and fingers are totally puffed up too.
Nothing really hurts, I’m peeing fine, my blood pressure is just low like it always is, and I don't feel lightheaded at all...
I tried sleeping with my legs propped up last night, which helped the swelling go down a bit this morning, but now it's just getting worse and worse again. It’s mostly just my left palm and fingers, and I can't even make a fist.

I'm honestly freaking out a little, like why is it only my left side? Ugh, I seriously do not want to deal with more doctor visits.😢

If you’ve got a rash that looks like mosquito bites, it sounds like hives to me. I had them all over my body once, and at first, I didn't even go to the doctor because I just assumed mosquitoes were out for blood...

..but I don't get why it would be swollen then..go see a doctor if it doesn't clear up in a day or two..

..if your foot is swollen right by the ankle..where is that bone located?..it could be fluid buildup..that can be kidney issues..my mom deals with that..you know this is just me guessing, though..

I’m pretty sure I dealt with hives too, and honestly, I have no clue if all this swelling is actually tied back to them.

Does anyone know what triggers hives? If it’s an allergic reaction to meds... well, that sounds exactly like me.

Look, there's really no other way around it—if this doesn't clear up, you're going to have to see a doctor.

It’s definitely possible that you're having an allergic reaction to the medication, of course.

So, I dealt with this hives situation over the summer, and honestly, I still have no clue what caused it. My doctor mentioned it might’ve been triggered by taking some Tylenol right before heading down to the beach. Apparently, you aren't supposed to go out into the sun after taking certain meds because of some chemical reaction or whatever. He also suggested I might be allergic to acetaminophen, which is weird because I've never had an issue with it before.

..if you took a pill, it's definitely possible that was the culprit, since a ton of them can trigger a rash...
