Thank you for the quick reply & sharing the picture.I have seen it.
The symptoms you have described of having tiny pinkish/red symmetrical bumps initially on neck,chest,nose,ears & now mostly on arms & torso since last 2 weeks are suggestive of skin disease known as urticaria.
A hypersensitivity reaction (similar to an allergy) occurs in the skin, causing inflammation. The inflammation causes the skin to become reddish & itchy.
Another possibility can be of a condition called petachiae.It appears when capillaries bleed, leaking blood into the skin. They are red because they contain red blood that has leaked from the capillaries into the skin.
You need following tests:
-Radioallergosorbent test (RAST)
-Antinuclear antibody(ANA) tests
You need skin allergy tests.Common one are:elimination-type tests.In this the suspected foods are avoided for several weeks and then gradually re-introduced one at a time and you will be observed for signs of an allergic reaction.
Radioallergosorbent test (RAST) is a blood test done to see whether there is true allergic reaction.
So my best advise for you is to make an appointment with your doctor to have these tests done so as to know the exact underlying cause & then treatment will be done accordingly.
Till then take tab.Zyrtec.It contains Cetirizine & is a second-generation antihistamine.It is now available over-the-counter (OTC).This will not make you sleepy & will help greatly to provide relief from itching.
Apply cream containing hydrocortisone.If the area is large then apply Calamine lotion.
Hope this helped.
