Blood clot: Four signs in your arm – ‘alert your doctor as soon as possible’

There are several signs and symptoms of blood clots. They are important to spot, as blood clots can cause deep vein thrombosis (DVT). This can be dangerous and you will need quick medical attention.

It adds: “If you have these signs or symptoms, alert your doctor as soon as possible.”

“If a clot plugs up veins in your arms or legs, they may look bluish or reddish,” explains WebMD.

The health site adds: “Your skin also might stay discoloured from the damage to blood vessels afterward.

“A pulmonary embolism in your lung could make your skin pale, bluish, and clammy.”

DON’T MISS:

There are also several signs of a blood clot in your speech, according to the American Heart Association. These signs include “trouble speaking or understanding speech, suggesting a possible stroke“.

Some risk factors put certain people at higher risk for developing a blood clot.

Blood clots become more common as people get older, especially when they are over age 65. Moreover, you can be at higher risk if you have a family history of blood clots.

Sometimes, a blood clot in a vein can occur with no apparent underlying risk factor.

If DVT is diagnosed, the main treatment is tablets of an anticoagulant medicine, such as warfarin and rivaroxaban. You will probably take the tablets for at least three months.

If you are pregnant or have just had a baby, your risk is higher. Similarly, if you have an inflammatory condition such as Crohn’s disease or rheumatoid arthritis, this can increase your risk of clots.

There are some steps you can take to reduce your risk.

For example, the NHS says you should drink plenty of water to avoid dehydration, as you’re more likely to get a clot if you’re dehydrated.
