My wife and I are short on funds and do not have health insurance. This is why I am enclosing a short video tape of her rash, in hopes that you can diagnose and prescribe. However, I'm afraid I cannot help you and am returning your tape. Of course, the appearance of certain skin lesions is frequently characteristic of a certain disease or condition but, not being a dermatologist, I don't feel comfortable diagnosing a rash unless it is attached to a living, breathing person whom I can question. I advise you not to put off medical attention because of financial reasons.
Most good physicians are willing to see needy patients for free, or for a reduced fee.
I'm confident that you can arrive at a compromise that will be to your wife's advantage. For example, you might be able to barter. One day, I saw a carpenter who badly needed treatment for an infected finger. I didn't expect to be paid, because he was temporarily unemployed. However, he suggested that he might perform a few minor repair chores in return for my medical skills.
