Hello

M y husband has had a mole appear on his head. It has appeared and grown in a matter of weeks. It’s pink ish and it was round and raised. Nurse said she’d refer to dermatologist but could be some time. Now (days later) it has almost deflated and become a bit less equal in shape with slightly jagged edges. It looks a little crusty at the edge. Should we get another opinion and ask for dermatologist appointment to be expedited? 
Thank you.
