You will need wear to compression/support stockings(full leg length) immediately after treatment and for 7 days following treatment. This helps with the efficacy of treatment.
You may have bruising, swelling, aching and or tenderness after treatment. It is common for the area to look worse after but this resolves itself quickly as the side effects of treatment settle down.
You need to wear SPF 50 on the treated areas, when exposed to daylight, throughout the course of treatment and for 6 weeks after your last treatment.
