Hi, have you got covid? long Covid can explain the sensations like Brain Fog, weakness, chronic fatigue, dizziness, and so on. Unfortunately from what I know, there aren't that many treatments to speak of. I started hyperbaric chamber treatment which helped me a little and I felt better after it. The cost of this treatment was very expensive and I am not sure if it is worth it. The doctors say that the symptoms should eventually go away, and I am also waiting for that to happen. How long ago did you get sick? How long have you had the symptoms?
