Welcome to our family. You've chosen a superb place to be. Everyone is so helpful and will andswer your questions, or just listen to how you are feeleing. Now to your questions. Because you mentioned the sun in connection with these little red bumps, I thought you might be interested in looking at a condition called Polymorphic Light Eruption - PLE for short.
I will give a brief synopsis of it, and then you can look into it further if it sounds familiar ok?
Polymorphic light eruption (PLE), otherwise termed polymorphous light eruption (PMLE), is a skin complaint caused by sunlight.
Typically, those affected by it will have been exposed to the sun for two to three days while on holiday, although the complaint does occur between the spring and autumn months in the UK, and sometimes as little as 15 minutes' exposure to sunshine can induce the condition. It can even be brought on by sunlight penetrating through a window or thin clothing.
A delayed-onset, spotty, itchy eruption appears on the skin, and may take between 5 to 10 days to clear.
The rash usually consists of small red spots or blisters and can appear on any part of the body that has been exposed to sunshine, although commonly the face and the backs of the hands will be spared. It tends to heal without scarring.
If possible try to take photographs of the spots whilst they are there, and then you can go to see your doctor and show him these to back up what you will be asking him about.
If I can be of any further help, let me know.
