I have little red pin sized spots on arms and legs. They cause no pain nor do they itch. Some are in small bunches while others are single dots. Should I be concerned? I read that working on high radiation area could cause this and I worked on a nuclear floor of a reactor for 7 years nearly 15 years ago. Thoughts?
The symptoms described by you are seen in multiple skin conditions. Physical examination of the affected area is essential to diagnose the condition.
Nuclear exposures have been associated with some skin and other cancers. But in case these spots are static, not showing any signs of growth and are not associated with any other symptoms, they are very unlikely to be because of a serious cause. Yet, the exact diagnosis can only be established by a skin biopsy.
I would recommend you to get yourself examined by a local dermatologist.
Hope that this information helps and hope that you will get better soon.
