Is There a Treatment for Bunch of Veins on the Foot?

A large network of spider and varicose veins on the foot is often referred to as corona phlebectatica. This may occur from genetic influences, hormones, environmental and occupational factors, and most importantly, ambulatory venous hypertension. Treatment should address the underlying cause of the distal extremity veins, rather than the spider veins themselves.

First of all, you would need to schedule an appointment with a vascular specialist.
During the first consultation, an ultrasound should be done to eliminate any problems with the main vein. Knowing that there is a healthy blood flow in your leg, the surgeon may suggest the sclerotherapy treatment - a series of injections of the solution to close off and shrink the diseased veins.
For large varicosities, ultrasound is often used to guide the injections into underlying vessels not seen on the surface of the skin. This delivers medication into a precise location safely and accurately to achieve superior long-lasting results.
In case there is a problem with the main vein, the laser surgery (EVLT) should be done first. Endovascular laser therapy (EVLT) is the most effective and least invasive procedure to treat many symptoms.
Ambulatory phlebectomy is also known as a successful treatment for varicose veins of the foot. Under local anesthesia, the diseased veins are delicately extracted using specially designed hooks. The incisions are truly stab wounds and are so small, no stitches are required and there is virtually no scarring.
With any alarming symptoms, it is always important to seek a medical advice and get help.

This can be signs of more serious venous disease higher up on the leg.
Just like a drip from your sealing may mean there is a pipe leaking somewhere, you need to identify and seal the leak in oder to stop the drip.
In venous disease this is often performed with an ultrasound machine. Once the proper diagnosis and source is made then the appropriate treatment can be initiated.
Ask your internist for a referral to a physician specializing in treatment of venous disease.

Thank you for the question! In my practice, I offer sclerotherapy, endovenous laser ablation, Clariven treatment, and microphlebectomy to treat varicose and spider veins. It's not a matter of one treatment being better than the other. Rather, the choice of treatment will depend on a size and location of your veins.  
In recent years, endovenous laser ablation (EVLA) has replaced traditional surgical method of treating varicose veins. This procedure uses laser to heat the veins instead of surgically removing them. The heat produces a steam bubble inside the vein, which destroys the vein walls, causing the affected vein to collapse. The body, in turn, naturally absorbs the dead tissue. 
Sclerotherapy tends to be one of the most popular and widely-used treatments these days. It uses a sclerosing solution that causes the vein to shrink. Usually, sclerotherapy takes only 1 to 2 sessions to achieve fading of the undesirable veins.  
Microphlebectomy is ideally suited to treat superficial bulging veins that are too large for sclerotherapy.  In the course of this treatment, I will make tiny incisions as small as 1mm to remove an undesirable vein.  He will then insert a small phlebectomy hook to extract the vein through the puncture.  Only a small section of the vein needs to be eliminated because the remaining portion of the vein will clot off and gradually fade from view. 
Clarivein is a minimally-invasive procedure that utilizes a thin infusion catheter clinically proven to deliver faster results and guarantee up to 74% less pain than most other peripheral vascular treatments. 
An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and obtain expert medical advice. Best of luck! 

This area of the body is notoriously difficult to treat with either superficial lasers or sclerotherapy although the latter would be a lot less painful and less likely to result in brown pigmentation and scarring.

You probably need an assessment for your whole venous system first.  Then the MD will decide on what larger veins need to be treated and then you can focus on those not-so-nice ones around the ankle.  Sclerotherapy is still the gold standard but should be approached with caution.
