Some conditions may also cause you to have blood or protein in your urine. If you have a urinary problem, see your healthcare provider. Urinalysis and other urine tests can help to diagnose the problem. Treatment depends on the cause.
Cold sores are usually caused by the herpes simplex virus (HSV) type 1, which is transmitted by such forms of contact as kissing an infected person or sharing eating utensils, towels, or razors. Genital herpes is usually caused by herpes simplex virus type 2.
Herpes simplex (or just Herpes) is another name for the cold sore virus. It commonly causes local blisters and scabbing around the mouth and nose but occasionally infects the eye where, unlike the skin, it may cause scarring or chronic inflammation. The cold sore virus is a different strain of herpes than the one associated with sexually transmitted disease; ocular herpes is not an STD.
