You had a aching left arm for weeks nowpain tables dont take it away and its night time when achs more?

Potential causes of left arm pain that worsen at night:

1. Angina: Chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood. It can sometimes radiate to the left arm.

2. Myocardial Infarction (Heart Attack): Severe chest pain that persists for more than a few minutes, often accompanied by discomfort in the left arm.

3.Aortic Dissection: A tear in the aorta, the main artery that carries blood from the heart, can cause severe chest and back pain that may extend to the left arm.

4.Peripheral Artery Disease (PAD): Narrowing of the arteries in the legs or arms, which can cause pain, numbness, or weakness in the affected limb.

5.Cervical Radiculopathy: Nerve root irritation in the neck, often due to a herniated disc, can cause pain that radiates down the left arm.

6.Brachial Plexus Injury: Damage to the nerves that control the arm can lead to pain, weakness, and numbness in the left arm.

7.Thoracic Outlet Syndrome: Compression of the blood vessels and nerves in the upper chest can cause arm pain, numbness, and tingling.

8.Costochondritis: Inflammation of the cartilage that connects the ribs to the breastbone can cause chest pain that may extend to the left arm.

Since the pain is persistent and worsens at night, it's crucial to seek immediate medical attention, especially if you suspect angina or heart-related issues.
