Skin rashes on the face in adults are commonly rosacea or acne, which are both harmless skin inflammations that can be easily treated with over the counter medication (OTC).

Hives (urticaria) are often noticeable as light-red, swollen and itchy rashes. Hives typically appear quickly and can even disappear quickly without leaving any skin marks.

Many childhood diseases such as chickenpox, urticaria, and three day fever cause harmless rashes, often in combination with a fever. Common viral infections can cause small red spots on the face or body that disappear for some time after the infection has healed. Also eczema, dry skin, heat rash and diaper rash are common in children.

Skin disease is one of the leading causes of global disease burden, affecting millions of people world wide. Aging, environmental and genetic factors, and trauma can result in the development of a diverse set of skin diseases, with over 3000 entities identified in the literature.

Patients with skin diseases make up about 6% (in Children < 15 years of age 9%) of the patients seeking in primary care, where most skin diseases can also be dealt with. Skin symptoms can be part of systemic diseases and a holistic approach is important as well as a good collaboration between skin specialist, primary health care and other disciplines.

These patches are on my legs, trunk and arms. It started 2 days ago and occurs in the evening/night as small wheals and flares then progresses to large, itchy, warm patches. It lasts for a few hours and mostly disappears in the morning with hardly any trace. I’ve been taking OCPs for the last 1.5 years. I have no known allergies. I’ve acquired a cold around the same time the rash appeared. 

Skin rash urticaria hives left arm legs trunk female

Online Dermatologist answer
Based on the information and images submitted, this is possibly a URTICARIA: Urticaria or “Hives”. They are frequently caused by allergic reactions; however, there are many nonallergic causes like medication, infection, heat, cold, pressure on the skin or an external irritant for example. This results in the release of the substance histamine in the skin, which causes local inflammation with swelling and gives rise to itching or burning, raised, red skin lesions known as wheals. These lesions have a tendency to move around and disappear within 24 hours only to appear again in other places. Over-the-counter antihistamine pills (e.g. Desloratadine 5 mg, once daily) are recommended to alleviate itching. Most often this will pass within a matter of days or weeks. If no improvement or if it spreads, see a dermatologist in person for a new evaluation and testing.

Male 32 years old from Ottawa Canada
Skin rash. Hello Doctor I’m so stressed and I have been on anti depressant for the last few months. My life is so miserable because of the disease that I have. I think most probably I have HIV. I went to few message parlor when I was in China 6 months ago which is Avery risky HIV country. Most of the times the girl was fully naked and I was fully naked. She slides all her body to my body. Her vagina and vaginal fluid came into contact with my back because she was rubbing her vagina on my back. Also, I used to finger those girls. Also, one time only I received unprotected oral sex from one of the girls at the massage place. I never practiced and vaginal intercourse. I know that those stupid activities are very risky and I have HIV by now. 3 weeks after my last fully nude body to body message I got a fever, sore throat, skin rash on my chest and on my shoulder, and a swollen lymph node under my armpit. As for the rash specifically, it started with the rash on my chest. then a week after my shoulder started to have a different type of rash as you see in the picture. The chest rash disappeared after 2 weeks but the shoulder rash is still active since 5 months. I’m really scared to death that I have given my wife HIV and I’m going to die. Few more things, I have been developing all HIV symptoms such as headache, shortness of breath and last month I had a diarrhea for new reason. – Does HIV rash look like this? 

Skin rash tinea versicolor left shoulder male stressed

 

Online Dermatologist answer
Based on the information and images submitted, this is possibly a TINEA VERSICOLOR (shoulder) and FOLLICULITIS (chest) : Tinea Versicolor is a fungal infection of the skin caused by the fungus Malasezzia Furufur. This condition typically occurs in warm humid climates. It is treatable but can recur especially in individuals who swim or are in outdoor, warm water environments frequently. An over-the-counter shampoo such as selenium sulfide or ketoconazole can be helpful. The shampoo can be lathered on the chest, back and abdomen daily for 10 minutes for 1 week, then can be repeated once weekly for maintenance. If no improvement in approximately two weeks, then a dermatologist should be consulted for an in person evaluation and possible prescription treatment. Based on the information and images submitted, possibly FOLLICULITIS (chest): Folliculitis is a very common skin condition. It is caused by an inflammation of the hair roots. This condition is commonly a consequence of shaving or having a lot of hair on the skin. Shaving or irritation can cause small openings in the skin allowing bacteria and other irritants to enter and inflame the hair follicles. It can be both infectious (skin bacteria involved) or non-infectious (inflammation alone). Applying a topical steroid cream (eg hydrocortisone 1% sold over-the-counter) twice daily for a week may help. Also, cleaning affected areas with antibacterial soaps or solutions (e.g. Chlorhexidine). Cleansing the areas of the body like the chest, back and thighs that are prone to folliculitis with over the counter benzoyl peroxide 3 days a week may help to prevent the folliculitis flare. (Benzoyl peroxide containing washes may fade the color out of your wash clothe, towel, and clothing, so many people use a white/old wash clothe/towel, use it at bedtime and sleep in an old t-shirt. Also, avoid shaving until the lesions have cleared. A visit with a dermatologist is called for if no improvement in 2 weeks. The rash of acute HIV may be non-specific. It can have similar features as a rash due to a different type of virus and is therefore may be difficult to diagnose. The current images are more closely related to the conditions above. However, due to the concern for HIV infection and contact with at-risk partners, HIV testing is necessary. Public health departments and primary care providers are available to do do HIV testing. Some centers even offer inner cheek (Buccal mucosa) swabs that will provide a result within minutes. There are many people living with HIV. The most important thing to do is to get tested. The result may be negative or positive. However, delaying taking the test may impact your health and put your spouse at continued risk. Seek support from a therapist, if needed, to take the steps necessary to gain the courage necessary to get tested. Best of luck and well wishes.
