What is a sign of arm pain and hand swelling?

Arm pain and hand swelling can be a sign of several medical conditions, some of which may be serious. It's important to see a doctor if you experience these symptoms, especially if they are accompanied by other symptoms such as chest pain, shortness of breath, or dizziness.

Some possible causes of arm pain and hand swelling include:

* Deep vein thrombosis (DVT): This is a blood clot that forms in a deep vein, usually in the leg. DVT can cause arm pain and hand swelling if the clot travels to the lungs (pulmonary embolism).

* Peripheral artery disease (PAD): This is a narrowing of the arteries in the legs and arms. PAD can cause arm pain and hand swelling when the arteries become blocked or narrowed, reducing blood flow to the limbs.

* Lymphedema: This is a buildup of fluid in the tissues, which can cause swelling in the arms and hands. Lymphedema can be caused by damage to the lymphatic system, which is responsible for draining fluid from the tissues.

* Cellulitis: This is a bacterial infection of the skin and underlying tissues. Cellulitis can cause arm pain and hand swelling, as well as redness, warmth, and tenderness in the affected area.

* Rheumatoid arthritis: This is an autoimmune disease that causes chronic inflammation of the joints. Rheumatoid arthritis can affect the joints in the arms and hands, causing pain, swelling, and stiffness.

* Osteoarthritis: This is a degenerative joint disease that causes the breakdown of cartilage in the joints. Osteoarthritis can affect the joints in the arms and hands, causing pain, swelling, and stiffness.

* Tendonitis: This is an inflammation of the tendons, which are the cords that connect muscles to bones. Tendonitis can cause arm pain and hand swelling, especially if the tendons are located in the arms or hands.

* Carpal tunnel syndrome: This is a compression of the median nerve, which runs from the forearm to the hand. Carpal tunnel syndrome can cause arm pain and hand swelling, as well as numbness, tingling, and weakness in the hand and fingers.
