About 3 days ago I noticed clusters of pinprick red blood spots on the outside of my thighs.They seem to have cleared but I have now developed some on the inside pf my thighs. They are red/ purple in size and range from pinprick to a bit larger. I do bruise fairly easily but never had these before. I also had problems with clotting in past with DVT and superficial clots but not recently. Any ideas?
