I am 43 years old, I have a very itchy spots at the back of my head. Biopsy check confirmed it is not cancerous, my doctor and skin specialist have tried freezing, use antibiotics and resently have Surgically removed some of the spots which have reduced it somewhat, but not totally such that it itches realy bad. Please, Am I being diagonized wrongly and what can I do to permanently fix this itching problem.
