Fro Charlotte - My husband has the problem of a feeling of swelling of the head accompanied with dizziness and nausea.  We have been to see our heart doctor and an ENT but both of the doctors felt his condition was not something that they could diagnose.
Hi thereby your question I am assuming that he feels there is a swelling of head while there actually is no real swelling of head this is associated with vertigo and nausea this may actually be a PCA infarct would suggest you get a MRI brain with Mr angiography as soon as possible please note my judgement is limited by the information you provided have no idea about his age, habits, prior medical issues and medicines best of luck
