A blood clot, also known as deep vein thrombosis (DVT), occurs when blood accumulates or clots in one of the deep veins of the body. According to the Mayo Clinic, blood clots are a serious concern because they can detach themselves from the veins and travel through the bloodstream to the lungs. Once in the lungs, a blood clot can impede proper lung functioning. Blood clots can develop in veins anywhere in the body, including the arm. Recognizing the symptoms associated with a blood clot in the arm can provide signals that medical treatment should be sought.
Once the blood clot forms in a vein of the arm, it is common for patients to experience swelling in the affected part of the arm or the entire arm. This swelling stems from the inflammation of the vein that contains the blood clot. This is most noticeable when one arm appears different than the other. Swelling in the neck may also occur when the blood clot develops in the arm, states the Mayo Clinic.
Redness or Warmth
Many patients notice a warm spot near the area where the blood clot has formed. It may feel like a warm sensation or the area may actually feel warm to the touch. In addition, the area may appear red and inflamed.
Soreness or Pain
As the blood clot worsens, a patient may experience soreness. It may resemble a mild aching initially but can become very sore over time. In moderate to severe cases, the affected area can become painful. The pain may resemble muscle soreness or may feel more deeply rooted, like joint pain.
In the most severe cases where the blood clot travels to the lungs, patients may have difficulty breathing. Some patients develop a cough and if it becomes severe, they may cough up blood. An accelerated heartbeat or chest pain may also occur. Some patients suffer from a fever and may feel faint. If a patient suspects he may have a blood clot, he should contact his doctor immediately as complicated symptoms of a blood clot can develop quickly.
