hi I have a mild brain injury, which leaves me very forgetful and delirious at times. I have had multiple head and facial reconstructive surgeries over a 6 year period due to a car accident in 2009. I Suffered psuedomunus in my frontal skull wall, bone and obliterated frontal sinus as a result, then filled with hydropoxy bone cement to fill holes in the frontal skull.  been 4 years since last surgery, still suffer migraines regularly, I eat healthy and keep active and fit with my home gym as much as i can. But the last 6 months I having moments of dizziness, almost like i have consumed a lot of alcohol. i get confused and delirious a lot more, have episodes of tightning of the skull and everything goes black for 20-30 seconds and upto a minute, where i just have to sit wherever i am until it passes. I have been unusualy tired, bruising a great deal, and horrendous frontal skull pain some days, still chronic migraines, terrible upper back and neck pain, lack of apetite, dehydrated, although drink litres of lemon water and home made fruit juices with wheatgrass ect... I feel hot flustered and sick a lot, pretty much a blocked nasal passage most days, but no flu..the pain is unbearable at times, but ive always had pain and just deal with it in the ways i learnt in pain management rehabilitation...I went to local doctors, had blood tests and iron levels ect.. fine....is it a result of the Bone cement?? A reaction??      Shelley

HIT hank for asking to ChatDoctorI can understand your concern looking to your surgical history, if your brain is intact (Hypothalamus, cortex) then there won't be question of memory loss, you have gone through the multiple repairs and natural that it must have pushed you into the shock, and you have to come out of this, you seem to have some functional disorders too, and that might be causing such symptoms you just take it easy and have nice day
