When you say that you have HPV, do you have genital warts or another strain that's caused cervical dysplasia? I ask because if you are concerned about warts on your throat, it is the strains that cause the majority of genital warts (6 and 11) that are responsible for the majority of laryngeal warts. This condition is, however, extremely rare, and is called recurrent respiratory papillomatosis.
The best advice that anyone can give you is to go see a doctor and have them checked out. You may require a biopsy to figure out exactly what the bumps are, it is very difficult to diagnose yourself.
In the meantime, since you say you have HPV, the only real way to fight it is via your own immune system. Here are some tipson how to boost your own immune system so that it can better fight the HPV virus in general:
1. Diet: eliminate all refined, process, pre-packaged foods and sugar. Increase your daily intake of fresh fruits and vegetables to 8-10 servings a day (1 serving = 1/2 cup). Make sure you are eating enough protein (very important to immune function).
2. Supplements: a good quality probiotic, Vitamin C, and a product I love called Papillex (designed specifically for HPV infections) will all help boost your immune system.
3. Exercise and stress management - also vital to overall health and immune support. Opt for minimum 30 minutes a day of mild to moderate exercise, such as brisk walking. Or buy yourself a rebounder (those mini trampolines) and jump on that for 30 minutes a day
Hope this helps
