sun rash on arms - treatment/prevention?

Have tolerated for many years small red spots on forearms, which redden considerably when exposed to sun.  I enjoy the outdoors.  When exposed, they itch, and some flaking of skin around the spots.  Turn noticably bright red when exposed to direct sun.  In construction, work outdoors a lot.  Also on upper arms, though not exposed to sun as much.  10 years ago was prescribed Carac cream (spelling?) to no avail, also very expensive.  Also deal with some pigmentation loss on spots on back due to sweating (tropical acne it was called many years ago) used coal tar shampoo, didn't seem to help much. Dime to nickel size maybe 8-10 spots.  But red spots on arms are the most annoying, and unsightly.  Very much would appreciate your advice.  Thanks

Thank you for your quick response.  A question if I may...If it is indeed pruritus, is there a topical ointment or treatment above and beyond sunscreen (I usually use 35+ SPF) that could eliminate the rash?  These spots are on my arms 24/7, all year.  Somewhat dry, and unsightly.  I will proceed with the antifungal approach for the pigmentation issue as the summer season when this occurs is about upon us here in Charleston, SC.  Would appreciate any comments on 'cure' or elimination of the rash on my arms topically or otherwise.  Thanks!!!

HI,

Sun rash or solar dermatitis are seen as small, reddish blisters or spots in areas that have been exposed to sunlight. This may be associated with pruritus and has a tendency to recur.  Try to avoid the 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, eg sun hats, sunglasses with proper UV protection and clothing material that doesn’t allow the sun through easily. A sunscreen with a high sun protection factor (SPF) is important. With regards to your back, these spots could be due to tinea versicolor, a fungal infection that may respond well to over-the-counter anti-fungal medication. If it persists, have these evaluated further bu a dermatologist for proepr management.

Take care and regards.
