Compression stockings are medical grade devices designed to move blood flow. 

Support compression stockings are made available in multiple compression support levels. Most commonly compression support stockings come in mild (8-15 mmHg), Medium (15-20 mmHg), Firm (20-30 mmHg), X-Firm (30-40 mmHg) gradient compression levels.

Compression Therapy Guide

Mild	Provides relief and minimizes tired and achy legs. Prevents fatigued legs from long periods of sitting or standing. Helps relieve minor swelling of feet, ankles, and legs.	During pregnancy, helps prevent the formation of varicose and spider veins. Helps maintain healthy, energized legs.
First Time Wearing Compression Stockings? We recommend you start with 15-20mmHg
Medium	For the prevention and relief of minor to moderate varicose and spider veins. Helps relieve tired, aching legs, and minor swelling of feet, ankles, and legs. During pregnancy, helps prevent varicose veins and spider veins.	Helps prevent deep vein thrombosis (DVT), also known as economy class syndrome. Used in post-sclerotherapy treatment to help prevent the reappearance of varicose veins and spider veins. Ideal compression level used for those traveling long distances.
Firm	Helps prevent and relieve moderate to severe varicose veins (also during pregnancy). For post-surgical and post-sclerotherapy treatment to help prevent the reappearance of varicose and spider veins. Helps in treatment of moderate to severe edema or lymphatic edema.	Helps with the management of active ulcers and manifestations of post-thrombotic syndrome (PTS). Helps relieve superficial thrombophlebitis. Helps prevent orthostatic hypotension (sudden fall in blood pressure when standing). Helps prevent deep vein thrombosis (DVT), also known as economy class syndrome.
Extra Firm	Helps prevent and relieve severe varicose veins. Used in the treatment of severe edema and lymphedema. Used in post-surgical and post-sclerotherapy treatment to help prevent the reappearance of varicose and spider veins.	Helps reduce symptoms of Orthostatic Hypotension and Postural Hypotension For the management of Venous Ulcers and manifestations of Post-Thrombotic Syndrome (PTS). Prevents deep vein thrombosis (DVT), also known as economy class syndrome.
RX	40-50 mmHg Gradient Compression Stockings are generally indicated for more Serious Venous Diseases such as Acute Leg/Ankle Swelling, Varicose Veins, Chronic Vein Insufficiency and Deep Vein Thrombosis.

The benefits of Compression Therapy are plentiful and the reasons vary from person to person why you may choose to wear compression socks or stockings. As shown in the above chart, some of the most prevalent symptoms or conditions that benefit from compression therapy are:

• Pregnancy related swelling and vein problems
• Varicose or spider veins
• Lymphedema or edema
• Swelling, pain or blood clots in the lower legs, also known as DVT (Deep Vein Thrombosis)
• Poor circulation from sitting for long periods
• Post-surgical and post-sclerotherapy treatment

It can even be used as a preventive measure to maintain healthy legs for someone who spends extensive amounts of time on their feet. Quite simply, when we stand still for long periods, the forces of gravity increase the pressure within the veins of the legs where the greater effects happen at the ankle and decreases gradually up the leg and body. This pressure depends on the vertical distance of the column of blood from the heart to the foot. That's why gradient compression stockings are designed with the pressure greatest at the ankle and diminishing as it moves up the leg in order to counter the effects of the higher venous pressures.

Compression therapy products are put on in the morning upon arising, which is typically before any significant swelling would occur, and then removed at night. Throughout the day the compression prevents blood from pooling in leg veins, which in turn helps your overall circulation and lessens or eliminates any leg swelling you may have.

When shopping for compression socks or stockings, it is best to measure earlier in the day before swelling builds in the legs. Measurements taken later in the day after swelling occurs may cause you to choose an item that is too large and then not effective.

There are many types of compression socks and stockings available without a prescription and they do offer wide-ranging benefits. Before wearing a compression therapy of 20 mmHg (Firm Compression) and above, it is generally recommended to consult your health care provider to find out if graduated compression stockings are right for you. If the answer is yes, they can tell you what pressure grade you should buy for maximum benefit and relief.
