If you wear very tight socks, sock marks will appear on your legs the moment you remove themafter a long day. However,your legs may be signalingunderlying health conditions. Peripheral edema is one of them.If the marks are mild and do not happen often, then you should not worry. If the marks recur ortheswelling gets worse,it could be a sign of a chronic health problem such as diabetes or heart disease.

Sock indentation marks often take the exact shape ofthesocks worn. These indentationsarenot normal even when they happen occasionally and should be evaluatedby a health professional.

PeripheralEdema is The Most CommonTrigger

Yourfeet, ankle,and lower legs are the most common places you will see edema resulting from fluidbuildupin yourbody.Defined as palpable swelling resulting from increased fluid volumes in a tissue, itcan happen in any part of your body. But because of the forces of gravity, it appears aspainless swelling in the lowerextremitiesof your body.Understandthat there is localized and generalized edema.Generalizedappears intheform of collected fluid volumes in many body organs,and localized occurs in certain parts of your body. Leg edema is the most commonlocalizedtype.

Peripheraledema isnot painful and is mostly caused by a systemicproblem withinyour kidney or heartor issues with veins within the area affected. If youonlyhave swellingsin the legs withoutpitting, you could be having problemswithyour lymphatic system or thyroid.Pitting edema is when indentations are left when pressure is appliedbehind on the skin.Theskin around the affected areamayfeel heavy andtight, andcouldalso appear stretched and shiny.

HowDoes PeripheralEdema Occur?

Edemaoccurs when fluid from the capillaries flow inside the interstitial space.The condition can be a clinical sign of various diseases, with its progression often accompanied by physiological changes.Itis a process triggered by increased pressure within the smallest blood vessels – the capillaries. Capillariesdistributeoxygenated blood to tissues and transportitto the veins from the tissues.

Pressure build-up withinthecapillariesforceswater out of the blood vessels and distribute it in the tissues. This then leads to an increase of protein inthebloodcausing more fluid to be pushed back tothevessels. Thefactors contributing totheformation of periphery edema include:

• Obstructed lymphatic drainage
• Increased hydrostatic pressure
• Increased vessel wall permeability
• Water retention in tissues
• Increased tissue oncotic pressure

What CausesPeripheralEdema?

Older people are at a higher risk ofhavinglarge collections of fluid around the feet. Standing or sitting for too longcanalso cause swelling. After taking off shoes or socks, you may notice socks indentation marks. Thesigns are not alwaysa cause for worry, unless thepitting doesnotclear up quickly. One of the most serious causes of peripheraledema is venous insufficiency.Certain antidepressants such as blood pressure medications canalsocontribute to theoccurrenceof edema. Shouldyouswellwhen you’re undermedication, let your doctor know.

VenousInsufficiency

Venous insufficiency is a condition that can be signaledby swollen feet andsock indentation marks. If you havehad clots inyour legs, you may be at risk of this condition. When the walls of the veins inside your legs become weak, and the valves repelling blood into yourveinsget damaged, venous insufficiency is likely to occur. Because of the damage to the valves, some of the blood flows back and collects in the veinsof the legs and feet. Compression stockings, in this case,will be necessary tomaintaina steady flow of blood. Avoid tight socks that could leave indentations behind.

When to See Your Doctor

Persistent peripheral edema needs aphysical examination for proper diagnosis.Because some conditions linked to sock marks and swelling are serious, theunderlyingcause needs to be established. Edema resolves after the treatment oftheunderlying cause. A detailed medical history, imaging tests, urine, and blood tests may be needed.

If only one leg is affected, there could be apossibilityof cellulitis. Sock marks could also be a sign of existing blood clots in the leg, a condition known as deep vein thrombosis. Report this to your doctor immediately to prevent the clot from finding its way to the lungs. Should it settle in your lungs,pulmonary embolism, a fatal condition could set in.

Peripheraledema becomes more apparent with age and canoftenbe controlled with home care such as elevating the legs,limiting the dietary intake of sodium, and standing less. If it persists, it may be a signal of severe illnesses such as congestive heart failure. Reporting sock marks to your doctor early enough can be a means of preventing edema complications.
