Thanks for all the replies, Bros. Gave K where I could.
Well, the Dr. perscribed me amoxicillan for the infection. I told her everything, (after I read their privacy policy and found it ok). She was really cool about everything, but I gotta say, not so knowledgeable. So much so in fact, that a less tactful person than myself might reflect on her gender and her minority status and be tempted to make some comments about the possibility of affirmative action contributing to her position.
...But you'll get none of that here, folks
In any case, I am going back Sunday for a follow up. She said it might have to be lanced. As long as everything is in order by Tuesday, and I can head out to Mexico, I can live with that.
I'll keep you posted...
