Shingles, hives, psoriasis, eczema and rosacea are some common skin conditions in adults, according to WebMD. Other sources of skin conditions include cold sores, rashes from plants and razor bumps.
Herpes zoster, commonly called shingles, appears as raised bumps that form into blisters, WebMD explains. It results in tingling, burning and itching skin, frequently noticeable on the buttocks and trunk of an infected person. Although the initial infection lasts approximately two weeks, the itching, burning and pain may linger for months, years or a lifetime. Some treatment options are antidepressants, antiviral medicine, steroids and creams.
Causing itching, burning and stinging, hives closely resemble welts in appearance, states WebMD. Varied in size, they can be visible for anywhere from several minutes to several days. Hives occur as a result of an allergic reaction to foods, medications and food additives; extreme temperature changes; or infections such as strep throat. Skin creams and antihistamines may be helpful.
Psoriasis is detected by thick, red patches of skin that have white or silver scales, WebMD, describes. Psoriasis forms after a person's immune system makes new skin cell growth too rapidly. Appearing on elbows, knees, the scalp and lower back, psoriasis is treated with skin ointments and creams, oral medications, intravenous fluids, injections and light therapy.
