Brief Answer: Allery, platelet disorder are most probable Detailed Answer: Hello, Thanks for posting your query on Healthcaremagic. Development of spots all over body suddenly raises the possibility of allergic reaction in the first place. However, you have mentioned that you do not have any history of allergy in the past. Despite of the fact that you do not have a history of allergy, the possibility of allergic reaction cannot be ruled out. You need to get a complete hemogram done to look for the status of red blood cells, white blood cells and platelets. Decrease in number of platelets or any functional abnormality of platelets can also cause pin-point sized petechial hemorrhages. A sudden onset of pin-point petechial hemorrhages also raise the possibility of platelet disorders. Consult your physician at the earliest for clinical examination and relevant investigations. If you have more queries, I will be glad to answer. Dr Shailja P Wahal
