When should spider veins get checked?

You notice a fine red or blue line on your leg and wonder whether it is a cosmetic nuisance or a reason to pick up the phone.

The change that turns a nuisance into a phone call

my.clevelandclinic.org words its rule plainly. Call a healthcare provider if: A spider vein — or any blood vessel — appears swollen or red/discolored, or it feels warm or tender when you touch it (signs of a blood clot).

Notice what the rule watches. It is not the number of veins or how they look from across the room. It is swelling, color change, warmth and tenderness, which the source ties to a possible blood clot.

Reading further before you decide

The spider veins page is the source for that rule. For context, the venous disease overview and the page on varicose veins show the wider family of conditions, and MedlinePlus gives a second publisher to compare against.

This page serves readers across Mokena and New Lenox.

What to ask when you do go in

If your vein matches that description, say so first and ask what the clinician thinks it is before any treatment is discussed. If it does not, ask what changes would make them want to see it again.
