Shingles

Questions to Discuss with Your Doctor:

• Do you have a history of chicken pox?
• Does your skin hurt, itch, or feel numb?
• Is the pain sharp, dull, or piercing? How long have you had it?
• Do you have a rash? If so, for how long?
• Is the rash in more than one place on your skin?
• Is the rash on one side of your body only?
• Has the rash at any time looked like small blisters?
• Do you still have pain even if the rash is gone?
• What triggers the pain (for example, a light touch)?
• Do your symptoms interfere with your ability to sleep or perform activities of daily living?
• Are you taking any medications?

Your Doctor Might Examine the Following Body Structures or Functions:

• Skin exam almost always confirms the diagnosis

Your Doctor Might Order the Following Lab Tests or Studies:

• Skin scraping to examine under the microscope, or for viral culture, immunofluorescence, or polymerase chain reaction testing (rarely needed)

Dr. Robert S. Stern, chair of the Department of Dermatology at Harvard-affiliated Beth Israel Deaconess Medical Center , calls them "solar-phobes": people so concerned about getting skin cancer that they stay inside or cover every bit of skin. "They cover up like they were going out into the Arabian Desert ," he says. The marketing of ultrablocking sunscreens and special sun-protective clothing plays into these fears.

There's no getting around the fact that sunlight is hard on your skin. Age gets blamed for wrinkles and rough, dry skin. But the real culprit is a combination of age and sun that dermatologists call photoaging. The short UVB wavelengths that cause sunburn can also damage DNA and suppress the skin's immune system. The longer, more penetrating UVA wavelengths may create highly reactive oxygen molecules capable of damaging skin cell membranes and the DNA inside.

It's often said that our lives are written on our faces. But if you feel like doing a little editing—erasing a few fine lines, softening a deep furrow, or evening out some patchy spots—there's an increasing array of products and procedures to help rejuvenate skin worn by time and sun exposure. "When it comes to skin treatments, there's lots of good news in therapies for medical conditions as well as cosmetic concerns," says Dr. Kenneth Arndt, adjunct professor of dermatology at Harvard Medical School and medical editor of the Harvard Special Health Report Skin Care and Repair.

A growing population of healthy, active older women who want to look as young as they feel has spurred the development of skin rejuvenation techniques that are more subtle and have much shorter recovery times than facelifts. "It's important to choose your treatments with care and to check and double-check the reputation and accreditation of clinicians performing invasive skin procedures," Dr. Arndt says. You may want to consult a dermatologist to weigh the possible risks and likely benefits of various treatments. Cosmetic procedures aren't covered by insurance, so cost might also be an important factor in choosing a skin rejuvenation procedure.

Many products are designed to absorb water into the skin, keep it from evaporating, or both.

If you grew up watching Doris Day movies, you may have assumed she was privy to skin treatments that weren't available to the general public. However, as she revealed in her autobiography, Vaseline (petrolatum) was the key to keeping her skin soft and smooth.

Things have changed quite a bit in the last 50 years. Petrolatum is still a popular staple, but there is now a dizzying array of newer moisturizers, many with a baffling list of ingredients on their labels. However, they all are designed to either add moisture to the skin or keep it there. Many do both. "Think of moisturizers as putting a barrier between your skin and the cold, dry air," says Dr. Kenneth Arndt, professor of dermatology at Harvard Medical School and faculty editor for the Harvard Health Publications Special Health Report Skin Care and Repair (www.health.harvard.edu/SCR.)

Once you've completed treatment, adjusting to a "new normal" can be challenging.

Completing cancer therapy can feel like a graduation. You've done some hard work, it's paid off, and you may be ready to celebrate. But saying goodbye to treatment can arouse many of the emotions and uncertainties associated with beginning a new chapter in life.

Dr. Larissa Nekhlyudov is a general internist who works with cancer survivors at two Harvard affiliates, Brigham and Women's Hospital and Dana-Farber Cancer Institute. She acknowledges that cancer survivors have a lot to deal with. "Once you've had your final chemotherapy infusion or swallowed the last pill, you may find yourself facing a new set of challenges—monitoring yourself for signs of recurrence, getting recommended follow-up care, adjusting to the long-term effects of treatment, psychologically adapting to normal life, and working to stay in good health," Dr. Nekhlyudov says.

Venous insufficiency, which happens when veins don’t work properly, can cause swelling, pain, and a sense of heaviness in the legs. Elevating the legs when sitting or lying down can help; so can support stockings. 

Droopy eyelids, known as ptosis, are often a normal occurrence of aging although some neurologic conditions also can cause the condition. Ptosis is not a serious problem unless it interferes with your vision. If this happens, or if your droopy eyelids are bothersome, you can opt for cosmetic surgery to repair your eyelids.

Sun protection is essential whenever you are outdoors. Self-tanning products offer a safe alternative for attaining that sun-kissed look.

Gone are the days when we were urged to soak up the rays to get a healthy glow and absorb the "sunshine vitamin." Decades of medical research have determined that sun exposure causes skin cancer and that a nutritious diet and supplementation are reliable ways to obtain the vitamin D essential for good health. In other words, there is no good reason to expose your skin to the sun's ultraviolet (UV) radiation.

There is no such thing as a healthy suntan. "A tan is a response to DNA damage," says Dr. Barbara Gilchrest, a dermatologist at Harvard-affiliated Massachusetts General Hospital. Such damage is instrumental in the development of skin cancer, and it also accelerates skin aging. "Some women may tan well for many years, but eventually the skin quality will change, become leathery, develop lentigenes ["age spots"], and then coarse wrinkling," Dr. Gilchrest says. If you're a lifelong tanner, compare the skin on the underside of your upper arm or buttocks to a tanned area, and you'll see evidence of the changes wrought by UV radiation.

Men may not be doing all they need to protect themselves from sun damage and skin cancer.

Proper protection against skin cancer continues to be relevant once a man hits age 65. "Unfortunately, ultraviolet [UV] exposure and damage is cumulative over our lifetimes," says Dr. Joseph Merola, a dermatologist with Harvard-affiliated Brigham and Women's Hospital. "There is no safe age at which we can put down the sunscreen or stop thinking about sun protection."

Even if men are aware of the dangers of sun exposure, new research shows most do not follow basic guidelines. A study published June 17, 2015, in JAMA Dermatology found that only 14.3% of men surveyed reported they regularly use sunscreen. The study also found that men were more likely than women to never use sunscreen—43.8% of men compared with 27% of women—and perhaps most telling, only 7% knew what to look for on a sunscreen label.
