Strange smell (ora), dizziness followed by nausea and sweat?

I have be experiencing an ora (strange smell) which is immediately followed by a terrifically brief dizziness (wave, as the doctors have interpreted) and afterwards feeling rather nautious. I have done an EEG and MRI, no results on the other hand. Symptons have be going on for approximately 6 to 8 months. Very spuratic, sometimes no occurences for a few weeks. Any ideas on what this might be? I'm thinking a vitamin less. I am a 36 years old womanly. No past vigour history. I look after myself, eat right and other on the move.

What hormone is inhibited by the production of progesterone?

Could be any number of things like hormonal imbalance, seizures, or brain tumor. To me it sounds similar to a seizure. People can own such slight seizures (Absence seizures) where on earth no one really recognize it as a seizure, to the regal mal type. Which is what people typically ponder of when they hear seizure. There are abundant different kinds though. Good Luck, I hope it turns out to be nil serious.

It could be migraines, diabetes, Lupus, MS, thryroid problems. (or 2-3 of the above...) so ask the Docs to do some tests, TSH (thyroid), ANA (lupus), brain scan (MS)...

I have hear these symptoms as an indication of a brain tumor, but I also get them when I enjoy very low blood pressure. If you achieve dizzy moving suddenly or when you stand up, you most likely hold low BP, not likely to show up on an EEG or MRI. I would carry as many second opinion as it takes to find out the mete out. Also go to a shop that sell herbal medicines and vitamins, ask to speak to a qualified staff partaker and they should help you. But this is probable to be a long term entry, not a quick fix.
