**The following is a general guideline from the American Medical Association. The flowchart below allows you to easily track your symptoms and come to a possible diagnosis. Be sure to consult with you doctor if you feel you have a serious medical problem.

SYMPTOMS		DIAGNOSIS		SELF-CARE
Begin Here
1. Is your face, chest or back covered in small, pus-filled sacs or pimples, blackheads or sore, red bumps?	Yes	This may be ACNE, a common skin problem that often begins in adolescence.		See your doctor if over-the-counter acne treatments, such as benzoyl peroxide, don’t help. Gently washing your face with mild soap on a regular basis may be helpful. Sometimes prescription medicines, such as an antibiotic, may be prescribed by your doctor.
No
2. Do you have a flushed appearance, perhaps with redness around your cheeks, chin, forehead or nose?	Yes	This may be ROSACEA, a skin disease that affects the face.		Treatment isn’t usually needed, but antibiotics may be useful for moderate to severe symptoms.
No
3. Do you have a painful red bump or a cluster of painful red bumps?	Yes	This could be a BOIL. A cluster of boils is called a CARBUNCLE. These occur due to infection under the skin.		Gently compress the boil with a warm cloth. Use antibiotic ointments if needed. Call your doctor if the boils don’t come to a head, open and drain, or if the redness spreads.
No
4. Do you have a small, boil-like infection around a hair shaft or pore?	Yes	This could be FOLLICULITIS, an infection of the hair follicle.		Most of these will heal on their own. Clean the area. Use antibiotic ointments if needed. See your doctor if the condition worsens or doesn’t improve.
No
5. Do you have red, tender and swollen areas of skin, perhaps around a cut or scrape?	Yes	This could be CELLULITIS, an infection of the skin.		Clean the area carefully with soap and water and apply an antibiotic ointment. Call your doctor if redness and pain increase.
No
6. Do you have red, itchy bumps on your skin, and are they sprinkled randomly?	Yes	These could be INSECT BITES.		These aren’t usually harmful. Use hydrocortisone cream, antihistamine and ice to relieve itching. If symptoms get worse or don’t clear up, call your doctor. If new symptoms arise, such as difficulty breathing, dizziness or nausea, go to the emergency room right away.
No
7. Do you have irregular, raised or flat red sores that appeared after taking medicine?	Yes	This could be an ALLERGIC REACTION to the medicine.		Call your doctor. Try an antihistamine for itching and rash.
No
8. Have bumps formed suddenly on your face or body?	Yes	These could be HIVES, a skin reaction to an allergen, medicine or infection. They can also appear in some people who are very nervous.		Use an antihistamine and cool compresses for itching. If the hives don’t go away on their own or are accompanied by other symptoms, such as swelling around the lips or trouble breathing, see your doctor or go to the emergency room right away.
No
9. Do you have a red, itchy, scaly and oily rash, and does it affect the areas around your eyebrows, nose or the edge of your scalp?	No	Go to Question 12.*
Yes
10. Is the person an adult?	Yes	This could be a sign of SEBORRHEIC DERMATITIS, a condition in which the sebaceous glands overproduce.		Try using hydrocortisone cream or selenium sulfide shampoo on the sore areas. See your doctor if the symptoms continue or spread.
No
11. Is the person a child and does the dry, scaly skin cover the head?	Yes	This could be CRADLE CAP, a form of seborrhea in infants.		Try gently scrubbing the scales to remove them. Hydrocortisone cream may also help. See your doctor if the rash doesn’t go away or if the hair doesn’t grow in that area.
No
*12. Do you have a red, scaling rash, and did it begin after contact with clothing, jewelry or perfume?	Yes	This could be IRRITANT CONTACT DERMATITIS. It’s caused by a reaction to detergents, perfumes and other substances.		Avoid whatever you think caused the symptoms and treat the area with hydrocortisone cream or other soothing lotions.
No
13. Do you have a red, itchy rash, and are blisters forming?	Yes	This could be ALLERGIC CONTACT DERMATITIS, caused by POISON IVY, poison oak or poison sumac. The oil from these plants causes an ALLERGIC REACTION.		Wash the area with soap and water to remove any oil that remains on the skin. The rash will go away after about a week. To relieve itching, apply hydrocortisone cream or calamine lotion to the rash. See your doctor if the rash covers a large area of your body, does not go away, or if new symptoms, such as fever, appear.
No
14. Are there red, swollen, tender bumps in your armpits or other areas where hair grows?	Yes	This could be HIDRADENITIS SUPPURATIVA, inflammation of the sweat glands.		See your doctor. Avoid using antiperspirants and deodorants.
No
15. Do you have small red dots on your skin, or larger, bruise-like spots that appeared after taking medicine?	Yes	This could be ALLERGIC PURPURA, a serious allergic reaction to a medicine, such as an antibiotic that can cause bleeding.		See your doctor right away.
No
16. Do you have a rash that started with a single scaly, red and slightly itchy spot, and within a few days, did large numbers of smaller patches of the rash, some red and others tan, break out over your chest and abdomen?	Yes	This may be PITYRIASIS ROSEA. The causes aren’t known.		Check with your doctor. Calamine lotion and antihistamines may relieve itching and redness. The rash will probably go away in a few weeks. Pityriasis rosea doesn’t usually respond to treatment.
No
17. Do you have an intensely itchy rash with red bumps and blisters, and does it appear on your elbows, knees, back or buttocks?	Yes	This may be DERMATITIS HERPETIFORMIS, a rash associated with a sensitivity to gluten, a protein found in cereal grains such as barley and wheat.		See your doctor. Antibiotics can help control symptoms. Avoid foods that contain gluten.
No
18. Do you have large, red bumps on your skin that seem to bruise, and are they tender to touch?	Yes	This could be ERYTHEMA NODOSUM, possibly caused by an infection or reaction to a medicine.		This condition usually isn’t serious, but see your doctor to check for other diseases or causes of your symptoms.
No
19. Do you have a white, scaly rash over red, irritated skin, possibly on your elbows and knees?	Yes	This could be PSORIASIS, a condition caused by the overproduction of skin cells.		See your doctor. Keep the skin moisturized. Your doctor may prescribe ointments, oral medications and/or light therapy, also called phototherapy, to treat the symptoms.

21. Do you have a red rash that is raised on your forehead and face, then spreading to your neck, trunk and downward, and do you have a fever and sore throat?	Yes	This could be MEASLES, a virus that often affects children.		See your doctor right away. Make sure your child gets an MMR immunization to help prevent this disease. Be sure to keep the affected person away from pregnant women, as measles can lead to birth defects.
No
22. Do you have multiple blisters on your face, chest and back, and spreading downward, along with a fever, cough, aches, tiredness and sore throat?	Yes	This could be CHICKENPOX, a virus called varicella-zoster that most often affects children.		See your doctor. Treat symptoms with acetaminophen, cold medicines and anti-itching creams, cool compresses and baths. A vaccine is available to prevent this disease.
No
23. Do you have red blisters that are extremely painful and that may crust?	Yes	This could be SHINGLES, a herpes-zoster viral infection of the nerves.		See your doctor. Analgesics, such as acetaminophen or ibuprofen, and cool compresses may help.
No
24. Is the person a child or an adult who had a fever and then developed a bright red rash covering the cheeks?	Yes	This could be FIFTH DISEASE.		Use cold medicines to treat symptoms. See your doctor if the rash is widespread or if you are pregnant.

25. Do you have soft bumps forming that don’t itch or cause other symptoms?	Yes	These could be WARTS. PLANTAR WARTS appear on the feet. Warts also commonly appear on the hands. GENITAL WARTS appear in the genital area and are a type of sexually transmitted infection.		For most warts, you can try over-the-counter treatments. If they don’t work, see your doctor about freezing them off. If the warts appear in the genital area, see your doctor. These warts shouldn’t be treated without your doctor’s care.
No

Women with irritation inside the vagina should first see their doctor before using over-the-counter yeast infection medicines.
