Sclerotherapy treats spider and smaller varicose veins by injecting a solution that causes the treated vessels to close. While the procedure is quick, the post-treatment period requires careful management of physical activity to ensure the best outcome. Movement is actively encouraged immediately following treatment, but the intensity and type of exercise must be controlled. Following a tailored activity plan helps the treated veins heal properly and supports healthy blood circulation in the legs.
The Mandatory First 24 Hours of Movement
Immediate, light movement is required after sclerotherapy. Patients are advised to begin walking almost immediately, often taking a 10 to 20-minute walk before leaving the office. This initial activity is crucial because it activates the calf muscle pump, the natural mechanism that drives blood back toward the heart.
Frequent, short walks (10 to 20 minutes every hour while awake) are recommended throughout the first 24 hours. This gentle motion supports the treatment by helping the treated veins stay closed. It also significantly reduces the risk of deep vein thrombosis (DVT) by preventing blood from pooling in the deeper veins.
Low-Impact Activities Approved for Early Recovery
The focus shifts to maintaining activity that promotes circulation without stressing the healing veins. Low-impact activities are approved for the initial recovery phase, typically spanning the first week. Walking remains the preferred and most effective exercise, often including a daily 30-minute walk at a comfortable pace.
Other gentle movements are also considered safe, such as stretching, light yoga (avoiding inversions), or using a stationary bicycle at a low resistance. These exercises engage the leg muscles to aid blood flow without generating excessive pressure that could compromise the treatment. Throughout these activities, prescribed compression stockings must be worn diligently. They apply continuous pressure to the treated area, minimizing swelling and supporting the closure of the injected veins.
Timing the Return to High-Intensity Exercise
Returning to a strenuous routine requires patience and a clear understanding of what constitutes high-intensity activity. High-impact exercises, such as running, jogging, high-impact aerobics, and heavy weightlifting, must be avoided because they increase pressure in the abdomen and legs. This pressure elevation can potentially reopen the treated veins or cause irritation, swelling, and bruising, delaying the healing process.
Physicians typically advise waiting at least one to two weeks before reintroducing these activities. The exact timeline can vary based on the extent of the treatment; procedures involving larger veins may require two to four weeks. When resuming weightlifting, particularly movements like squats or deadlifts, start with very light weights. Also, avoid breath-holding, which dramatically spikes internal pressure.
Heat and Water Avoidance
Certain environments must be avoided during the recovery window because they can cause the treated veins to dilate. This includes prolonged exposure to heat sources like hot tubs, saunas, steam rooms, and hot baths, especially during the first week. Soaking in water, such as swimming, should also be avoided until all injection sites have fully healed to prevent infection. Gradual progression and clearance from a healthcare provider are the best criteria for fully resuming a pre-treatment exercise regimen.
