Headaches can be caused by several reasons, but often the root cause is a viral flare up of shingles. It is important to stay well hydrated, and lemon water can be more beneficial than regular water in hydrating and flushing out neurotoxins. Avoiding foods that trigger a migraine can be very helpful, as can reducing stressors. Checking your child's eyesight is also important as vision changes contribute to headaches.
Additionally, if a headache is chronic, progressive, and wakes your child from sleep or there is a change in balance, speech, or other neurological symptoms- these all indicate that further evaluation is needed. Consult with your healthcare provider to discuss ways to reduce the frequency and severity of headaches in your child. Often lifestyle changes and stress reduction make a huge impact and improves overall health and wellness.
