Skin condition granuloma annulare, a woman who craves cornstarch, and more

Q: I have granuloma annulare and would love to find out if you have any information on ways to cure these raised spots on my skin. I have them on my hands, wrists, elbows and shoulder. I know that they sometimes disappear after a year or two; however, I have some spots that are persistent. Is there any remedy that you have come across? I'd love to beat these little guys!

A: Dermatologists don't know what causes granuloma annulare. Although unsightly, this skin condition is not at all dangerous. It often disappears by itself eventually.

One reader reported that after applying white vinegar to the skin, the bumps went away. A listener to our radio show had success using original Vagisil, an over-the-counter treatment for vaginal infections. It contains resorcinol, an old-fashioned antimicrobial ingredient that also has antifungal activity.

Q: I have been eating Argo cornstarch since I was 19. It started when I was in my first pregnancy, and I've been eating it ever since. I used to eat a box a day, and I think it is making me gain weight. I'm trying to cut back, but it's hard. I also have a very low blood count. I have tried everything possible to stop, but nothing is helping. I'm 33.

A: Your low blood count may provide the explanation. Ask your doctor about correcting the anemia. Low iron or zinc levels can sometimes trigger pica, a craving for nonfood substances. Cornstarch and laundry starch are common objects of cravings, but we also have heard from readers who crave ice chips or even foods such as popcorn, carrots or radishes. Usually these cravings disappear once the deficiency is eliminated.
