Japanese Mystery - Chronic Veinous Insuff.

Hi all. In 1995, I went with Indiana University to Iwate Prefecture in Japan. I was staying in a very small town called Towa - cho. As I played softball in my shorts, I noticed I had long black insects on my legs which I made nothing of. The next day my left leg was badly swollen. This swelling lasted for about three days. I really did not mind the purplish, reddish welts that were on my ankles as a result of this trip to Japan, until May 2000, when one of the little craters started squirting blood profusely. Applying pressure, the bleeding stopped. Then for about a year nothing happened. Last Monday, the little ex bug bite did its thing again and bled profusely but with pressure stopped. One doctor said I had necrotic vasculitis -- he is a General Prac. who is Japanese. He suggested Laser Surgery. Then, more recently, a vascular surgeon said to forget about laser surgery, and just to wear medium compression stockings. Please give me your opinions !!!!Thanks.
