What are the signs and symptoms of thrombosis?

Thrombosis is a condition that occurs when a blood clot forms within a vein or artery, blocking blood flow and potentially resulting in serious health complications. The signs and symptoms of thrombosis vary depending on the location of the clot and can include:

• Swelling in a limb—swelling often signals that there is an obstruction in one of the veins or arteries near your extremities; it’s important to seek medical attention if you experience any unusual swelling.
• Pain and tenderness —pain may be felt in the area where there is an obstruction from the clot, lasting for minutes or hours before subsiding. Tenderness may also be experienced at the site of obstruction.
• Discomfort when using muscles—if your muscles don't receive enough oxygenated blood due to a blockage, they might feel weak and uncomfortable when used normally.
• Changes in skin color —the area around where the clot has formed may turn pale, blueish, purple-hued (cyanotic), red (erythematous) or even black (necrotic).
• Fever —in some cases people with thrombosis can develop fever as their body tries to fight off infection that can result from having had an obstructed vein/artery for too long.

It’s essential to contact your doctor if you think you might have thrombosis so they can run tests such as ultrasounds or magnetic resonance imaging scans to confirm diagnosis and recommend treatment accordingly; not doing so could lead up to more dangerous complications such as stroke caused by prolonged lack of blood circulation throughout your body's organs due to blocked vessels.
