They are undiagnosed because no one has ever been able to figure out what is going on. Since last summer, (I live in a very hot and humid environment) I've had undiagnosed inner ear problems. There is also a history of high blood pressure within my fathers side of the family, but not too major.
I'm normally very calm and relaxed, although I probably do suffer from some stress due to work and other commitments. I plan to see a doctor but unfortunately I have a busy lifestyle which makes it hard to arrange an appointment. The glasses do not seem to have had much of an effect. I was told I didn't need glasses, but due to my job with computers and the amount of driving I do I was told I could get glasses to ease any strain. I had my eyes tested and found I had very slight eyestrain. Last year I saw a doctor about it who recommended I see an optician.
I think at the time I was fairly stressed out about the pressure so figured that may have caused me to believe I felt the spurting sensation. Additionally, a couple of years ago it got a bit worse and at one stage I had a slight sensation of liquid spurting out within my head beneath where the pressure was. The pressure and sickness seems to be a bit worse today. I have been back in the office for a couple of days now so I have been out of the sun and eating more regularly. I have wondered if it might be sunstroke, dehydration, or lack of salt, but it does seem to last about two or three months each year fairly regularly day to day. This year it started while on holiday and I had been in the sun a great deal. I have occasionally felt dizzy spells and occasionally have slight nausea. For a few years now, predominantly in the summer, I have felt a pressure on my head as if someone is pressing down with the palm of their hand.
