Its like a pimple but its been 1month its stil der in my head and wen i scratch it bleeds. hw dis wil be healed?

Skin Problem: It is difficult to answer a question about a skin lesion through a written description but typically pimples should not last for a month and bleeding when you scratch it also suggests that it may be a more serious problem. Consider having it looked at by a dermatologist.

Hard to tell: It is difficult to accurately assess over the internet. Generally, pimples last less than one week. Any lesion that has been bleeding for a month is best evaluated by a physician. See a doctor for an accurate assessment.
