Hi. I have been suffering from what I think is some kind of inflammation/tight sensation with slight tenderness of my back part of my head for last 2 years. Being in the sun sometimes aggravates it. A ct scan and spinal tap apparently showed nothing out of the norm except slight infection and slight effacement of sulci and basal cistern. Those doctors thought maybe it could be rheumatoid arthritis or the like. This condition comes and goes often for a day or so. I eat healthily(no sugar, low salt, plenty water and no stimulants) and am not obese. I sleep kindof alright between 4 - 6 hrs nightly. I take no medications and only run of the mill dietary supplements. I've had no head injuries of late except a suspected bout of severe heatstroke or viral encephalitis about 2 yrs ago, when all this started. One doctor e'en suspected my condition could be psychological, another hormonal...but none have been able to help. I do know that my issue 'is not psychsamatic' but definitely, something else. Please help. Justin Fairfield.
