I have not heard of anything about fevers and migraines and I have been personally dealing with head pain/migraines for many years. For a fever (even low grade) to last two weeks means there is something going on. I would have a discussion with your doctor. Aura, being uncomfortable, tired and drained are all possible signs of migraine. I just would hate to write it off as that and ignore possible some other underlying issue.
I apologize in the delay in responding to your post.
Has anything changed??? Any new symptoms?
