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.
About 10% of the cold sores are caused by herpes simplex type 2 and about 10% of the genital herpes infections are caused by herpes simplex type 1. Thus, for the most part type 1 is associated with the cold sores and type 2 is associated with the genital infection. This means that almost certainly your cold sores are caused by the herpes virus that typically does not cause the sexually transmitted disease.
