Welcome to health care magic.Moles
are pigmented lesions of the skin which are painless without itching and without any other symptoms.
If a mole is painful, has become itchy or increases in the size there is a reason to consult a local physician because there may be cancerous changes in this.
If the mole has started recently with the itchy problem then it may be an infection or dermatitis
rather than mole.
You should rather consult a local dermatologist
to get correct diagnosis and treat the skin lesions according to diagnosis.
I hope the advice will be helpful for you.
