Being able to communicate with Dr. Chang was a source of comfort the whole trip.

2 days after arriving in South Africa for a 23 day trip, my husband experienced pain and swelling in his jaw. He was unable to open his mouth. Even though there was an 9 hr. difference, I was able to discuss needed procedures and possible diagnosis. He approved the antibiotic chosen by a local Dentist.
During this same trip, my husband had a stone in his bladder that wouldn't pass.
