Ay alam ko yan, parang may "pins and needles" feeling sa scalp? Maraming possible reasons, from stress, tension headaches, poor circulation, or kahit nutrient deficiency, pero para sure, kailangan mo talaga mag-consult sa doctor para malaman kung ano exactly ang cause at ma-rule out kung may ibang concern. One of my mum friends had that din, at nung na-check niya, stress at dehydration lang pala, pero mas okay na siya after she managed both better, pero bawat tao iba, so really best na marinig ito ng doctor mo mismo para sa peace of mind mo.
