I have a tiny rash on palm of hand resembling a small cluster of tiny pin pricks that look like blood under the skin. It started with four tiny dots less than a week ago, now there is over twenty dots some more prominent than others. It is not causing me any discomfort and as far as i am aware i have not come into contact with anything unusual,there is no pain or itching. I am age 22, height 5ft 2 and weigh approx 62k, the only medication i am taking is yasmin, however 11 days ago i had 4 wisdom teeth out and took paracetamol and ibuprofen, i took the pain killers for 9 days.
