Have pain up and down left leg and left foot. I've been keeping it elevated all day. I hope its not a blood clot. I also took three Bayer aspirins.?

Once you mention . A blood clot, it must be ruled out. Blood clots can kill you. Please see your internist tomorrow. A venous duplex should be able to tell you immediately if a clot is present.
Check with A Doctor. If you have acute swelling along with pain and suspect acute clot DVT then you must check with er or your pcp asap because you need blood thinners like heparin/coumadin .. Aspirin does nothing for acute dvt.
See a doctor. The only way to rule out aclot would be to see a doctor and havea deuplex ultrasound test done.
