Sclerotherapy: vein injection treatment

Sclerotherapy uses carefully placed injections to close selected veins so the body can gradually clear them.

A clinician injects a sclerosant into a target vein. The solution irritates the inner vein wall, helping the vessel seal; circulation continues through other veins. It is commonly considered for spider veins and may be used for selected varicose veins after an assessment of vein health.

People can feel a brief pinprick with each injection and sometimes a short-lived sting, cramp, or pressure along the treated vein. The clinician can work steadily, explain each injection, and adjust positioning if you feel uncomfortable. Tenderness afterward is usually managed with the aftercare plan provided.

Sclerotherapy is a medical procedure and should be performed after a clinician reviews your veins, health history, medicines, allergies, pregnancy status, and circulation. Most effects are local and temporary, such as bruising or tenderness, but uncommon complications need prompt assessment. A tailored plan helps decide whether injections are appropriate for the veins being treated.

A treated vein can fade gradually as the body absorbs it, while the tendency to develop new visible veins can remain. Results therefore depend on the vein type, the response to treatment, and ongoing vein pressure. Your clinician may review progress after healing and discuss whether further treatment is useful.

The appointment is usually performed in a clinic. Treatment may focus on appearance, symptoms, or both, but it does not replace evaluation of swelling, skin changes, or circulation concerns. Compression may be advised to support the treated area after the appointment.

Sclerotherapy may suit adults bothered by visible superficial veins or selected symptoms linked to them. It can be one option for Spider Veins, and a vein assessment can clarify whether larger Varicose Veins need a different approach. New leg swelling, warmth, marked pain, a wound, or sudden shortness of breath needs urgent medical attention rather than cosmetic treatment.

The clinician examines the area, confirms the treatment plan, cleans the skin, and injects the chosen veins with a fine needle. Gentle pressure or a dressing may follow. You may be asked to walk after treatment and to follow specific instructions about compression, activity, bathing, and sun exposure.

Walking is often encouraged soon after the appointment, while your clinician may ask you to avoid activities that place heavy strain on the treated area for a short period. Mild bruising, firmness, itching, or colour change can occur as veins heal. Keep follow-up appointments so persistent veins or unexpected symptoms can be checked.

Possible effects include bruising, temporary skin discolouration, small tender lumps, inflammation, and recurrence or new visible veins. More serious concerns can include an allergic reaction, skin injury, or a clot. Contact the treating clinic promptly for increasing pain, expanding redness, a skin blister or wound, major leg swelling, breathing difficulty, chest pain, or fainting.

Depending on vein size and skin tone, options can include observation, compression when clinically advised, treatment directed at underlying venous disease, or Pulsed Dye Laser Treatment for selected small visible vessels. Stasis Dermatitis may need skin care and assessment of the circulation driving the inflammation, rather than an injection alone.

Choose a licensed clinician experienced in assessing leg veins and treating complications. Ask how the target veins will be examined, which Sclerosant Solution is proposed, what compression is recommended, and how to contact the clinic if symptoms change after you leave.
