@fala I have been dealing with something similar. Have you noticed any correlation with your activity, what you eat or wjat youre doing? Mine started beginning of September. Initially felt like a haze, brain fog, sleep inertia that never went away. Turned into a pressure in forehead area. It has been persistent, everyday all day but comes in waves. Usually going from 2 to a 7 and anywhere in between. Not painful, but it brings crashing waves of, whats best described as anxiety. Cant sit still, I pace miles a day. Reduced sensation over whole body, cold and numb fingers, insomnia, loss of appetite, lost 15+lbs the first month. Its like a constant physical feeling of dread and fear. I cant drive and cant work, struggle to concentrate or sit still at all, let alone be able to sit and read or watch tv. Mri clear, ct of sinus is pending, all panels and other tests clear. Even went to dentist to check that box, teeth are perfect. Was prescribed sumatripan, it didnt seem to have any effect. Neurologist wants me to try prednisone, so i will be giving it a try. My last trip to urgent care they gave me toradol, anti inflammatory. I started feeling better by the time I left so I bought some 800mg ibuprofen and have continued to find some relief, never back to normal, but close enough that I can eat and sit still for more than a minute. It still spikes occasionally and is still always present, but much better than I was a month ago.
