San Marcos residents experiencing varicose veins, spider veins, swelling, or persistent leg discomfort can receive specialized care at the nearby Texas Vein Experts clinic in New Braunfels. The clinic’s board-certified vein specialists focus on diagnosing and treating venous insufficiency with minimally invasive, image-guided procedures.
Varicose vein symptoms can include aching, heaviness, swelling, itching, burning, cramping, throbbing, and legs that feel unusually tired. These concerns may become more noticeable after long periods of standing, sitting, driving, studying, working, or completing daily activities.
Visible veins do not always reveal where the circulation problem begins. Duplex ultrasound examines blood flow and helps identify valves that are allowing blood to move backward through the veins. The findings allow the vein doctor to plan treatment around the source and extent of venous reflux.
Texas Vein Experts works with most major insurance providers and offers free insurance verification. Coverage may include Medicare, Medicaid, HMO plans, and other insurance plans, depending on medical necessity and individual benefits.

Approximately 24% of adults in the United States have visible varicose veins, while an estimated 6% show evidence of advanced chronic venous disease.
San Marcos has a 2025 estimated population of 77,830 residents, an increase of 14.9% from the city’s 2020 population estimate base.
Varicose veins can develop when weakened or damaged valves allow blood to flow backward and collect inside the leg veins. The resulting pressure may contribute to visible bulging veins, swelling, heaviness, cramping, itching, and discomfort.
As chronic venous disease progresses, some patients may develop persistent edema, skin discoloration, inflammation, bleeding, or slow-healing leg ulcers. Duplex ultrasound can confirm whether venous reflux is contributing to these symptoms and guide the treatment plan.

Contact our vein clinic serving San Marcos to schedule a consultation and diagnostic evaluation.
Specialized vein care is available a short drive from San Marcos at our New Braunfels clinic on North Walnut Avenue. There, board-certified physicians evaluate concerns such as varicose veins, spider veins, leg swelling, and discomfort linked to venous insufficiency.
Rather than selecting a procedure based only on the veins visible at the surface, the care team uses duplex ultrasound to examine circulation and locate the source of abnormal blood flow. This diagnostic step helps determine whether treatment should address a larger refluxing vein, smaller surface veins, or both.
Based on the findings, your vein doctor may recommend radiofrequency ablation, VenaSeal, Varithena microfoam treatment, or compounded sclerotherapy. Each option is selected according to the affected veins, your symptoms, and your individual treatment needs.
Care is performed in the clinic using minimally invasive techniques. Most treatments take less than 30 minutes, and many patients return to routine activities the same day, depending on the procedure and individual medical needs.

Trusted by our peers to help with vein disease
Texas Vein Experts serves San Marcos residents from its New Braunfels clinic at 1423 N. Walnut Ave., Suite 101. The clinic provides duplex ultrasound and minimally invasive treatment for varicose veins, spider veins, and chronic venous insufficiency.
Common symptoms include aching, swelling, heaviness, throbbing, itching, burning, cramping, leg fatigue, and visible twisted or bulging veins. Symptoms may become more noticeable after extended periods of sitting or standing.
Varicose veins commonly develop when weakened or damaged valves allow blood to flow backward and pool inside the veins. Age, family history, pregnancy, excess weight, and prolonged sitting or standing may increase the likelihood of developing them.
Varicose veins caused by weakened valves generally do not disappear permanently without treatment. Walking, leg elevation, and compression stockings may reduce symptoms, but they do not repair the faulty valve or close the unhealthy vein.
Duplex ultrasound shows how blood is flowing through the veins and whether any valves are allowing backward flow. It helps confirm venous reflux, identify the affected veins, and guide treatment planning.
Treatment may involve radiofrequency ablation, VenaSeal, Varithena, or sclerotherapy. These procedures close unhealthy veins so blood can redirect through healthier vessels. The appropriate treatment depends on symptoms and ultrasound findings.
Most treatments take less than 30 minutes, and patients can typically return to normal daily activities the same day. Specific instructions may vary according to the procedure and individual medical needs.
Many insurance plans cover treatment when it is medically necessary and supported by symptoms and diagnostic findings. Texas Vein Experts works with most major insurance providers and offers free insurance verification before treatment. Seguin
