<s>[INST] Hello I am expierencing fatigue,insomnia,something effecting my brain and eyes, blurred vision , dizziness , seeing black spots and lines ,disorientation,nausea,unexplained weight loss (28 lbs.) In the past few months , brain fog , morning sickness and just had a hysterectomy in November of 2013 . This is not me I ve had to stop working and driving. I don t have anxiety other than what is happening with my health and same with depression. What could be causing this? [/INST] dear,the complaints you suggest from above history, points towards a pathology in brain.1) a possible poor blood supply to brain, which could be transient. An underlying heart related issues.2) a possibility of brain space occupying mass. A brain MRI scan will be helpful to rule out this cause.3) a spurious injury to brain leading minor blood accumulation inside brain. Here again an MRI Bain scan will be needed.4) a rare but psychological cause can be suspected, if no abnormality I detected on investigations.Therefore considering all these possibilities and facts, I suggest an urgent MRI brain scan with routine blood investigations, ecg to get done.I would like to know any history of cancer in your family and the cause for you undergone hysterectomy.hope to have satisfied you query.thank you. stay healthy. </s>
