Worrisome: Your history is indeed worrisome for a blood clot. I think an ultrasound of your lower leg is need to rule out a clot. I don't see how a blood test could rule out the presence of a clot. If anyone knows I would like to hear an explanation. Please seek medical help. ...Read more

My leg turns redish purple while sitting or standing, but fine while lying. Tingles too. Blood test says no DVT or clot. What else causes this?

My leg turns redish purple while sitting or standing, but fine while lying. Tingles too. Blood test says no DVT or clot. What else causes this?

Likely stasis: There are signs of congestion.
If pulses and inflow are good-normal. Then cyanosis edema are signs of congestion.
Can be from heart failure, tricuspid valve, or more likely venous insufficiency without a current clot.
On the left occasionally the vein is compressed and can lead to congestion.
See a vascular surgeon and get an on site opinion and followup. ...Read more

Aching arm after blood test. No issues when giving blood or blood disorders. Is it something horrible like a blood clot? Do I need to see Dr again?

Is it swollen, red: Or firm? If a superficial vessel gets a clot from a blood draw it will not travel to heart lung or brain. May have a mild thrombophlebitis. Use warm compresses and try advil (ibuprofen) or alieve. If red warm to touch or getting worse see a doctor to make sure it is not infected. ...Read more

Blood clot in urine and slight lower right abdomen pain. Got ultra sound and blood test, they found nothing. What is this, and how can I treat it?

Follow up with doc.: Can't treat it unless you know what it is. Blood came from somewhere between your kidneys and the tip of your penis. There are a lot of things this could represent. You need to follow up with your doc until they are certain there is nothing evil in your urinary tract. At the end of the day they may say they found nothing. That would be good news. ...Read more

I had an ultrasound for blood clots on Friday. Test came back negative. Last night while sleeping I got a sharp pain in my leg like a cramp. Is it possible that I got a blood clot over the last 6 days if I've been smoking? I'm not a regular smoker

I had an ultrasound for blood clots on Friday. Test came back negative. Last night while sleeping I got a sharp pain in my leg like a cramp. Is it possible that I got a blood clot over the last 6 days if I've been smoking? I'm not a regular smoker

Anything is possible: But a recent ultrasound being negative would make this very very unlikely. Blood clots in the leg cause swelling, persistent pain, especially when walking/ bearing weight. Often times there is redness and warmth affecting the leg as well. Night-time leg cramps are not associated with these clots often. Women on oral / implant contraceptives have a greater risk of blood clots while smoking. ...Read more

Lower left leg, ankle&foot pain&swelling. No circulation issue. Have had blood test, xrays&ultrasound. No clot. No doctor I've seen knows what it could be.

Hard to be certain..: It's asking a lot of us online to come up with an answer. Lots of questions and an exam needed to try. If the pain and swelling is localized to a joint, e.g., your ankle, then you may want to ask if you were tested for different kinds of arthritis, e.g., lyme, rheumatoid, other infection, or gout. Not sure what else to offer. Good luck. ...Read more

Would an ekg, blood test, chest x-ray, and echocardiogram diagnose a blood clot in the lung?

Maybe: If the blood test was a "d-dimer" and there were certain specific findings on your x-ray, maybe. The definitive test for a pulmonary embolus (blood clot in lung) is a ct angiogram. However, if you had a negative d-dimer, that makes it extremely unlikely that you have a pe. ...Read more

Chest pain right side? Have had CT scan, x-rays, stress test, ekg, ultrasound for blood clots on legs. All test came back normal. Any suggestions?

Prognosis is good.: It is not clear as to for how long the symptoms have been present. If all the described tests are entirely normal, serious and life threatening causes of chest pain have been ruled out.
In such cases symptoms usually respond to otc analgesic agents and resolve in a short duration. Should symptoms persist or get worse, a second opinion from another physician may be helpful. Good luck. ...Read more

44 year-old female with a history of DVT and stroke; on Warfarin daily now with right leg swelling and bilateral leg pain.....?

Need good ultrasound study and a cardiac echo: Was there a reason found for the stroke? A clot in the leg may travel to the lung, but should not normally be able to get to the brain. The most likely reason it did is a defect in the heart. An echocardiogram will help sort the heart out, and can guide a repair. A good ultrasound of the legs is necessary to see if there is a recurrent clot. If not, another consideration is Post-Thrombotic Syndrome - failure o the valves in the leg veins from scarring after DVT. Patients with DVT need to wear compression hose daily for at least 2 yrs after DVT to minimize the risk of PTS. ...Read more
