I have 2 bilateral hard bumps about an inch above hairline toward the center of back of skull. Are these occipital nodes?

Could be. If they get larger see your doctor, if not caused by infection they may be more serious condition.
Possibly. This problem can only be solved by seeing your doctor and being evaluated face-to-face. After a thorough examination, your doctor should be able to tell you what's wrong and what to do about it.
