Just got my shots 2 days ago from the Tijuana site. Got shots on my 2 shoulders, 2 knees, and right hip. The only pain I have are from the shots but they were tolerable. Dr. Ramon and his staff were great, informative, and professional. Spent some time getting to know Dr Ramon and I like his approach to life–from his dedication to his family, his belief of doing good to everyone/your neighbor, and his continuous research to stay ahead in his profession (he is currently writing a book on the subject as well).
