Hello everyone! maybe someone had such a problem .. Two years ago I felt something in my head, a heat, then a big headache .. A few days later I started to sleep a lot, about 18 hours and my vision started to double, to see badly, I started to have very big spasms in my head, my concentration disappeared, my thinking became slow. I went to the doctor and he had an MRI, they ruled out multiple sclerosis and other tumors. I did other investigations like: doppler, electroencephalogram and blood tests .. All went well, I went to the psychiatrist, he recommended me to take Escitalopram 20mg, I followed for a year and nothing changed, then I went to another doctor and he told me to try Venlafaxine 37.5mg and already for 8 months I followed and still nothing .. It's been two years and something, I feel just as bad, very weak, so feeling that my brain does not recover after many hours of sleep, double vision or foggy , memory affected, I can't do any activity, I don't have energy, I always want to sleep and I feel very hard spasm behind the head .. The other day I did some tests and ultrasound .. I did an analysis CA19-9, the norm is 37 for me it came out 89, could there be any connection between my condition and this analysis? Thanks.
