Is there downtime after sclerotherapy? January 24, 2023 Because sclerotherapy is a minimally invasive treatment, there is no formal downtime or recovery period associated with the procedure. Most patients are able to return to their normal daily activities, including work, following their sclerotherapy treatment in Houston. Following sclerotherapy treatments, it is normal to experience swelling, bruising, and general discomfort in the treated areas. This typically resolves on its own within a few days of treatment. While many patients may start to see the results of their sclerotherapy treatments after just one session, Dr. Downey or Dr. Bullocks may recommend up to a series of three to five treatments spaced a few weeks apart to achieve ultimate results.
