I suffered a spontaneous csf leak 4 months ago that seems to have healed naturally for the most part. I still get the odd feelings of pressure in my head especially with certain movements, ie. bending over, getting up too fast, etc. and stiffness/weakness in my neck and shoulders. I will be travelling in June which will be 9 months since the csf leak occurred, however, I am concerned about flying. Will I be able to fly?
