For the lactose intolerant: Don't get a Brazilian wax after indulging in dairy.

A sticky situation

I sweat a lot. Let me rephrase that: My armpits spurt bodily moisture like a high-pressure fireman's hose. I've tried everything to fix the problem -- clinical-strength deodorant, extra layers of clothing -- with little to no results. Last summer, I was a bridesmaid in my cousin's wedding, which was outdoors during the thick of the July heat.

Knowing full well I was going to sweat profusely, I decided to stick panty liners in the armpits of my cap-sleeved gown. It worked through the ceremony and photos -- no pit stains in the wedding album! By the time the reception rolled around and I'd had a few drinks, though, I'd forgotten about them. As I was dancing with a groomsman, one pad had come out and stuck to his shoulder. Health.com: Celebrity sleep secrets

"What's that?" he asked. I snatched it up and said, "Oh, just my shoulder pad." I don't know if he believed me, but I was impressed with my quick-thinking save. --Sadie, Dallas, Texas

What's that smell?

A week after my period ended, I noticed an abnormal discharge and a strong odor emanating from down below. I couldn't figure out what was causing it and why, so I scheduled an appointment with my gynecologist. During the examination, he pulled out an icky black lump, which he identified as a tampon. That's when I remembered that I had put in two tampons on a heavy-flow day and must had forgotten to remove one. Health.com: 25 diet-busting foods you should never eat

He threw it out, and then asked the nurse to remove the trash. It was obvious why -- the thing stunk to high heaven! Even though the doc told me not to worry because it happens often, I was beet-red with embarrassment and definitely learned my lesson about doubling up on tampons. Now I back up heavy-flow days only with pads. --Tina, Atlanta, Georgia

I gotta go!

When I was pregnant, I was sent for an ultrasound to make sure everything was OK. Because I wasn't very far along, I was told to drink a ton of water. I downed four big glasses before leaving home and took a bottle along for the ride to the clinic. By the time I got there, I was ready to explode -- and, of course, they were running late. I waited patiently at first, but as the urge got worse I started getting up every few minutes to ask how much longer.

Eventually, I just laid down across a couple of chairs and moaned. Finally, I begged the nurse to tell me where the bathroom was and that I would reschedule the appointment -- if I could please, please, please go pee NOW! I was rushed in to see the technician, who then made me go to bathroom because my bladder was too full for her to see anything. Go figure. --Patricia, Albuquerque, New Mexico

A windy waxing

I'm lactose intolerant, but I just can't kick my cheese and chocolate milk cravings. The unfortunate result of my dairy bingeing is usually gas, but I consider myself something of a flatulence ninja because I'm a pro at concealing it. That wasn't the case, though, when I recently went in for a bikini wax after a night of lactose gluttony. I wanted the full monty, so when the aesthetician was done with my front, she made me flip over on all fours. Health.com: 8 tips for telling your partner a health secret

As she smeared wax in the most nether regions of my behind, I just couldn't hold it in any longer and accidentally let one rip right in the poor woman's face. If that wasn't enough, I fell down laughing, which made my butt cheeks stick together from the wax, so the aesthetician had to separate them and re-apply. Let's just say she got a very big -- and (well-deserved) tip. --Sasha, Sheboygan, Wisconsin

A gross gag

I came down with a nasty sore throat and convinced myself it was strep. I canceled all my plans, whined to my friends, and went to an urgent-care clinic so I could get on antibiotics and back on my feet pronto. The doctor took one look at my throat and told me I had a tonsilith, also known as a tonsil stone, which is essentially just gunk (food particles, dead cells) that binds together and forms hard white balls that stick in your tonsils.

I could have waited for them to fall out or had the doc pluck them out himself. I opted for the latter. The doctor went in for the kill with a swab, but I'd forgotten to tell him about my very sensitive gag reflex. With one little nick of my throat, I threw up right on his arm. At least we were in a sterile environment and I had eaten a light breakfast. --Kate, New Brunswick, New Jersey

What's cooking?

When I was 21 years old, I got my first yeast infection while on vacation in Greece. A doctor recommended that I pick up some over-the-counter medication and gave me a list of helpful hints for treatment and prevention. I pored over the list and focused on the benefits of yogurt, so I picked up a carton of the traditional, thick Greek cultures and slathered the stuff all over my crotch -- right before boarding a 12-hour boat ride to one of the islands.

As the temperature got hotter, I became more and more uncomfortable, not to mention smelly. My cousins on the trip noticed, too. That's when I told them about my self-treatment, and they informed me that the yogurt was supposed to be eaten, not slathered on below! --Maria, Alexandria, Virginia

A "hairy" tale

Thanks to menopause and stress, I have drastically thinning hair, which I'm really self-conscious about. So late one night after a few glasses of wine, I ordered a "hair replenishing" product that was being sold on TV. When I received it, I realized it was basically just a spray designed to camouflage thinning spots on your head. I thought, What the hell. I ordered it, so I might as well use it.

And, although it did make my hair look less thin, I found out the hard way that it wasn't exactly waterproof. One day, I got stuck in a downpour during my lunch break -- and I returned to the office in my white shirt that sported a newly-dyed brown collar ... the same shade as my hair. --Denise, Keene, New Hampshire

R-rated undies

My husband and I were celebrating our five-year anniversary the same day I had to go to the doctor for a general checkup. Since I was going immediately to our date after my appointment, I dressed accordingly, meaning sexy dress and even-sexier panties. Health.com: 15 surprising ways to improve memory

I didn't realize that the doctor was going to do a full-body mole check and ask me to strip down to my bra and underwear (with a robe), and I immediately regretted wearing the G-string I had personalized to say "Happy anniversary, Tom. Your present is underneath."

I hoped the doctor wouldn't see it, but halfway through the screening, he said, "I take it Tom is a friend of yours?" I wanted to die. --Jocelyn, Boston, Massachusetts
