What should I do if my hand is swollen and painful after coronary angiography?

Hand swelling and pain after coronary angiography may be caused by normal physiological responses, allergic reactions, coagulation abnormalities, or other reasons, and can be improved through general management or medication. Specific analyses are as follows:

1. Normal phenomenon

Coronary angiography requires inserting a catheter into an artery or vein in the arm, which may injure the blood vessel wall or surrounding nerves, causing discomfort such as arm swelling, pain, or numbness. It is recommended to avoid strenuous activity, rubbing, or exposure to cold. Appropriate arm movement and massage may help relieve symptoms.

2. Allergic reaction

During coronary angiography, some patients may experience an allergic reaction to the contrast agent, manifesting as rashes, arm swelling and pain, redness, or swelling. Under medical guidance, patients may be treated with medications such as dexamethasone sodium phosphate injection or hydrocortisone injection.

3. Coagulation abnormality

Coagulation disorders, such as bleeding or hematoma, may occur during coronary angiography, leading to obvious arm swelling, pain, and purplish-red skin discoloration. Under medical supervision, patients may be treated with medications such as warfarin sodium tablets or rivaroxaban tablets.

In addition to the above causes, conditions such as rheumatoid arthritis, gout, or cervical spondylosis may also contribute. As various factors can cause localized pain, it is important to seek timely medical evaluation, undergo appropriate diagnostic tests, and receive treatment based on the underlying cause.
