Are symptoms like headache when bending, hairfall and pale skin related to brain-affecting problems?

Headache while bendi. Headache while bending is sinus or structural. Hairfall. Lots of reasons, hair dye, tight bandana, low thyroid, hair pulling etc. Pale skin (sometimes attractive). The three are probably not related though red-haired folks with pale skin tend to have higher rate of allergies which is a cause of sinus conditions with secondary headaches.
