For the past few weeks I have been having a very itchy scalp
, and it tends to spread to the back of my ears, neck
, arms, and hands. Becuase of my itiching, there is now red spots in those areas except my head and ears. They are beginging to fade but I was wondering is it a rash or allergic reaction? I dont have lice but once in a while I have dandriff problems. But if it is dandriff, wouldnt it just affect my head and shoulders?
