Hi, I have been suffering from Brain fog, weak Vision and difficulty concentrating. The is also constant head pressure behind the head. I am currently undergoing treatment for Fatty liver and am taking Pioz 15 mg, Aztor and Supracol pro. I also feel really tired. Hand and Legs feel strained ( Kind of Numb ) when I try to sleep. Even cheeks get numb at night. I also have sinus problem that makes it difficult to breathe. I have been getting only 4-5 hours sleep for the past week. Can this be a side effect of any of the medication as I've not felt like this before?? Please help.
