Small purple spots - allergy?

Hello. From time to time I get what i think is an allergic reaction to something (doctor's don't know what and neither do I beause the blood test does not show any allergies). I think it's an allergy because the part of the skin starts to itch. When I scratch it it small red spots appear. A couple days later the small red spots turn into slightly larger redish purple spots. These are usuallly concentrated in one area, e.g. chest or arm. That is why it's so wierd for me because it's not like it is all over my body, just a small spot. This has happaned many times before. I called my doctor and he didn't seem to think anything of it, but I am worried. Thank you.

These purple spots are petechial spots and they are caused by leakages of small capillaries into the skin.This is because your skin has easy bruisability. Anemia and deficiency of vitamins C, K, B12, or folic acid are the common causes of easy bruisability.Try taking iron tablets and multivitamins for some days and see if the symptoms improve.

Other causes are alcohol consumption,liver disease,SLE,aplastic anemia and leukemia.
If your symptoms do not improve after taking iron and multivitamin supplements,then pls consult a physician and evaluate yourself for the above possibilities.

Hope it helps.Take care and pls do keep me posted on how you are doing.

Thank you for your response. I think you are right. This only happens when I scratch the part of the body that itches due to an allergic reaction. I have very sensitive skin that bruises very easily. I'll try to get more vitamin C, K, and B12.

Thank you.
