I have a red spot, lower right leg, increasing over last year in size, now about the size of a dime. I am 67, 175 in weight, jogger and walker, 90 pushups and 110 sit up 5 out of 7 days a week average. I have been a missionary in Brasil for last 10 years. I have applied a 50/50 mixture of triple anti-biotic cream with 1 % hydrocortizone. I am preparing to return. Should I be concerned?
