The initial symptoms of strongyloides hyperinfection syndrome may include fever, haemoptysis, and wheeze. A chest radiograph may reveal pulmonary infiltrates, which can represent a combination of oedema, haemorrhage, and pneumonitis.
As you bring the underlying hormonal disorder under control, you should see the dark patches fade. If your underarm skin remains dark, try applying over-the-counter topical creams containing lactic acid or glycolic acid, which can help to exfoliate the dark patches. Another cause of underarm darkening, especially in women with brown skin, relates to external assaults on the skin. For example, chemicals in underarm products, such as deodorants and antiperspirants, can produce an allergic or irritated reaction. Excessive rubbing can have a similar effect.
Other Causes of Dark Circles. Dark circles under the eyes may be hereditary. Because the skin under the eyes is very thin, when blood passes through the area it can produce a dark color, much like the blue color of your veins. The thinner your skin, the more the circles will be evident. Another cause can be overexposure to the sun. Another much-ignored cause of dark circles is allergies.
