When i press on pimples on my face, my pores & skin turns bright red and i can see blood underneath. the pore stays red. worried about blood disorder?

Probably normal: This is most likely a fairly normal response to pressure over an already inflamed area of skin, however if there is bruising or if you note easy bruising in other parts of the body, bleeding gums, etc, then I would definitely see your physician. A simple lab test can determine if you have a blood disorder or not. Also, check if you're taking any meds that act as blood thinners (like aspirin)
