For the last three years, I have had dizziness, brain fog and sinus problems. Initially I thought it was because I had my thyroid removed, and have had problems since this, but it has never gone. Sometimes it isn't as bad as others, but it never truly leaves. ENT has said my sinuses are clear, and said it wasn't an ENT issue. I am terrified of a brain tumour, and it is taking over my life. I never know from one day to the next how bad it will be. I have had to get through really important days feeling like this, and it has just become my life, but it makes me so sad. Any advice would be gratefully received. Thank you!
