Trouble swelling and windpipe closing up while lying down?

Swelling (edema) and difficulty breathing (stridor) while lying down can be symptoms of a serious medical condition called superior vena cava syndrome (SVCS). SVCS occurs when the superior vena cava (SVC), which is the large vein that carries blood from the head, neck, and arms back to the heart, becomes blocked or compressed. This can cause a number of symptoms, including:

* Swelling in the face, neck, arms, and upper chest

* Difficulty swallowing

* Hoarseness

* Cough

* Shortness of breath

* Dizziness or fainting

SVCS is a medical emergency and requires immediate treatment. If you are experiencing any of the symptoms of SVCS, it is important to seek medical attention immediately.

There are a number of different causes of SVCS, including:

* Cancer

* Blood clots

* Infections

* Heart disease

* Radiation therapy

* Trauma

Treatment for SVCS depends on the underlying cause. In some cases, surgery may be necessary to relieve the obstruction and restore blood flow to the SVC. Other treatments may include chemotherapy, radiation therapy, and medications.

If you are experiencing any of the symptoms of SVCS, it is important to seek medical attention immediately. Early diagnosis and treatment can help to improve the chances of a successful outcome.
