I have a solid lump in gland under my right ear, been there since childhood. is this normal?no pain/fever but i'm often run down & eczema in that area

Normal? probably not: Are headaches normal? Well no, but it can be a common complaint. So, are solid lumps under the ear normal? Probably not, although there may be a reasonable explanation. Since you have had this since childhood, most likely this is not dangerous; however, since you are uncertain as to what this is, it deserves an answer. To determine the answer, you truthfully need to specifically ask your doctor.
