I am not pregnant, but my feet/ankles are very swollen. Why?!

I am not pregnant, but my feet/ankles are very swollen. Why?

First of all, I am NOT pregnant. There is no chance that I COULD be pregnant. My feet and ankles have been swollen to the point of being quite painful for the past 5 days or so. I have tried keeping my feet elevated, which helps a little, but not much. I don't spend much time on my feet at all, as I have a "desk job." I have searched online, but the only results I get are for pregnant women. Please help, someone! Does anyone have any idea why this is happening to me?

I am 25 years old, and yes, it is very hot where I live, but I've been living here in this hell on earth called Houston, Texas all my life and this has never happened before...I'm really worried...I want to go to see a doc but I don't have insurance.

First see how bad the edema is. Gently press your finger into your skin in a swollen area. Notice if your skin returns to normal or leaves an impression/depression. If there is a sustained impression, you have pitted edema. How many seconds until your skin returns to normal? If it's more than a couple of seconds, you may be better off going to the doctor, especially if elevating your feet and reducing salt intake doesn't help.
Diabetes can cause this. Diet can cause this. Blood pressure, lifestyle, fluid intake, vitamin deficiency or fluid/electrolyte imbalance are all possibilities. Congestive heart failure as well as liver or kidney disease are also possibilities.

You should get some bloodwork done to find out what's up. The doc will probably prescribe a diuretic. This can cause you to be drowsy and will also cause potassium loss (unless it's a potassium sparing diuretic) and will drastically increase urination.
