I agree with anna. Best of luck!
My advice is to educate yourself about hpv by reading articles from very reliable sources. I am not an expert about hpv, but I believe the majority of the population (75%?) has one form of it or another. It's a common virus found on surfaces, etc. I am not sure what strain you have and why you are getting warts from it. I had hpv, and I just had a pap smear, and I don't have it anymore. I improved my diet through nutrition and whole food supplements, and it cleared up. I don't think this will interfere with anything regarding a letter. That is probably only for serious contagious diseases, so my opinion is that you have nothing to worry about regarding that. Just ask your Doctor what that is referring to if you want to know. The point is to improve your own health, so that the hpv that you have can hopefully clear up. My advice is to read a real good book about nutrition.
