Online dermatologist question My husband who is 48 years old. just noticed tiny red dots (not bumps) on the lower shin/calf areas of both legs, approx 6в beneath knees and 1в above ankle. He is at tailend of a cold or sinus infection. Lots of coughing and head and chest congestion with clear mucous. This was his first time to take Musonex DM. Online dermatologist answer Thanks for the images of the legs and the history. It looks like it could be LEUKOCYTOCLASTIC VASCULITIS, an inflammation of small blood vessels in the skin. The typical red spots that appear on the feet, ankles and lower legs may sometimes spread up to the thighs and even to the trunk. This type of reaction is usually caused by a previous infection or new medication. Elevation of the legs and the use of compression stockings may be useful. Treatment of the underlying infection or removal of the drug causing this may of course help the lesions to clear quicker.

If no improvement is noted within 1-2 weeks, if the lesions should spread or if abdominal pains are present, I recommend that you see a dermatologist in person for blood work and possibly a skin biopsy, if needed, a treatment plan.
So you woke up this morning and noticed mysterious red spots on your skin. First of all, don t panic. Second of all, don t Google it. OK, obviously you Googled it a little bit because you re here, but luckily you ended up in the right place. The fact is it might be difficult, if not impossible, to self-diagnose this issue because there is a very broad range of conditions that cause the appearance of red spots. We talked to a few experts for the lowdown on what the most common causes of red spots are, so consider this article a helpful jumping-off point before you book an appointment with your derm. Here s a list of some of the top causes of red spots. Psoriasis Psoriasis is a condition in which the immune system gets angry at the skin, leading to red, scaly plaques, says , director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. Usually you ll see it on elbows and knees, but psoriasis can appear anywhere, including the scalp, lower back, nails, and even the genitals. Want to get even more specific? This is a genetic, autoimmune, inflammatory condition in which your skin cells divide too quickly and do not shed quickly enough, says Tsippora Shainhouse, a board-certified dermatologist in Beverly Hills and a clinical instructor at the University of Southern California. That s what creates the inflamed, scaly plaques.

According to Shainhouse, psoriasis is often associated with psoriatic arthritis, metabolic syndrome, elevated triglycerides, increased risk for heart disease, and obesity. Yikes. You can see why it s not something you want to ignore. Keratosis pilaris Noticing rough bumps on your arms, legs, or cheeks? Shainhouse says these are caused by the retention of keratin in the openings of the hair follicles and can be exacerbated by dry weather. While it does tend to improve with age, it can be managed with and , including , like salicylic, lactic or glycolic acids, she says. If these don t help, ask your dermatologist about trying a prescription retinoid. (We recommend the and $10. ) Cherry angiomas Shainhouse says these common, cherry-red bumps on the skin are made up of a group of dilated blood vessels. We are not sure why they pop up, but most people start to slowly develop them by age 30, she says. They are not dangerous and are not generally itchy or painful and do not usually bleed. They don t need to be treated, but can be treated with electrocautery, lasers, or shave removal. Folliculitis These small red bumps that develop on the back, chest, shoulders, and buttocks are caused by inflammation and irritation of the hair follicles and is sometimes related to and yeast on the skin, says Shainhouse. She suggests changing out of sweaty clothing as soon as possible post-workout, using salicylic acid-based wipes (we like ), using antibacterial and anti-yeast washes in the shower, and maybe even using a topical prescription antibiotic solution. Broken capillaries Red spots that appear on the face are often caused by broken capillaries, which are tiny blood vessels that run through the surface of the skin, says John Diaz, a Beverly Hills-based board-certified plastic surgeon.

Some of the most common reasons why these blood vessels break are due to a fluctuation in hormones, sun damage, and skin conditions, like , he says. Luckily, if it s hormonal the red spots will go away on their own and if it s sun damage or a skin condition, like rosacea, your dermatologist can discuss treatments with you. Pre-diabetes One good reason to have your mysterious red spots checked out by a derm is the possibility of diabetes. Because pre-diabetics are more at risk for skin infections, they can develop various types of rashes and bumps, explains board-certified dermatologist Joel Schlessinger. Granuloma annulare and eruptive xanthomatosis are common examples of this. Beauty products Schlessinger also suggests looking at the ingredients in the products, especially , you re using. Although hair dye is the most common culprit, other hair products can also cause skin redness, itching, and inflammation, including hairsprays, shampoos, and conditioners, he says. Often, these skin reactions are caused by added fragrances or propylene glycol. specifically contain an ingredient called isopropyl myristate, which can clog pores and lead to acne if its not properly rinsed from skin. Best way to find out if one of your fave products is the cause of your spots? Avoid lathering up with them for a few weeks and see if the spots go away.
