my mother aged 81 has tingling legs, she said kinda like under the skin, and kinda itchy, however, it is not on the skin, it s in the legs . also, she has an itchy scalp and has a couple of red spots. are these two symptoms connected, and what could be the cause of both/either? My mom doesn t know if she should seek help from a family practitioner or a dermatologist...... whatdo you think?
