Welcome in H.C.M.
I have gone through your query regarding swollen glands behind the ears along with hair fall
As you have told that enlarged glands behind the ears are a chronic condition and there are episodes of enlargement of glands, whenever there is glandular enlargement automaticaly hair fall follows. All these part of your story favours that your scalp
may be diseased and the enlarged nodes should be investigated by FNAC to find out the real pathology behind it.
I would like to suggest you to please consult any dermatologist
for further management.
