Itchy Red Blotches

[te204]

I live in the tropics, during humid months I breakout in seriously itchy red blotches, can occur almost everywhere, although more often than not, crutch, thighs, arms & torso. I can temporaryily kill it with 'dharni lotion', an alcohol based blotch cure, but it will pop up again, in a different place next time. Then again in the same place after a period of time. It doesn't expose itself in the cooler months of the year, but thrives, and comes out when we go through the same hot humid conditions.

Would appreciate any info. with regards to a permanent cure for the above !

If this is the case,  miliaria or sweat rash occur occur when the sweat gland ducts get plugged due to dead skin cells or bacteria. The trapped sweat leads to irritation or prickling. The papules may  occur at a number of areas including the face, neck, under the breasts  or in skin folds and areas of the body that may rub against clothing.  Try to wear light clothing and to avoid activities that induce sweating,  as well as hot and humid weather. Have this evaluated further for proper management.  Direct clinical examination is important.

Thanks for the reply,

My problem seems to be directly related to the combination - humidity, sun & physical activity, ie if i sweat. The sun alone won't bring it on, and as you suggest, it isn't effected in the cooler months, but grows & comes out when the above conditions prevail.

Hi,

A sun rash or solar dermatitis is seen as small, reddish blisters or small or large spots in areas that have been exposed to sunlight.  This rash usually appears after exposure to the sun and can be extremely itchy.  Those who suffer from it get relief only during the winter and usually disappears as they get older. Avoid direct sunlight when it is most intense around midday and early afternoon. It is important to keep in the shade and to wear appropriate clothing (sun hats, sunglasses with proper UV protection and light clothing material)  Use a sunscreen with a high sun protection factor (SPF). If it persists, have this evaluated by your dermatologist for proper management.

Take care and regards.
