I feel constant pressure in my face and a heaviness in my head. I also get really nervous and shaky and even my knees appear to tremble. At some points I feel stomach cramps and pass a lot of gas! I feel so dizzy, I can only lay or sit down! I feel like I am going crazy! The doc gave me rhinocort nasal spray, antibiotics and clarinase, she also told me to do a CBC blood test! Will someone please help me with some additional information, feel like am going mad because I am already on sick leave and I fear this may affect my job! I need help please! Thanks!
