Ay nako, dizziness at weakness for three months, that's something you really need to check with your doctor as soon as possible, ha? Pwede itong maraming dahilan, at kailangan talaga ng proper checkup para malaman ang exact cause. A few of my mum friends experienced something similar, at iba-iba ang solusyon depende sa what was causing it, kaya important talaga na makita ng doctor mo. Get yourself checked, okay? Take care of yourself!
