I have a headache that has not gone away for over a week now. it's not that severe but i feel it on the right hand side of my face and head. my sculp is sensitive when i touch it there. it also seems that my right foot and arm has some pain?

Sinusitis: Sinusitis can be a chronic problem. Small changes in hydration and wellness can cause a flareup of the symptoms, including pressure/pain/fullness above the eye/within the cheek. Inflammation can lead to secondary infections when fluid builds up and allows bacteria/viruses to grow. Use saline nasal washes, decongestants and if infected, see a Dr for Antibiotics. Regular prevention = avoid symptoms
