Ay, itchy bumps kasi? Depende kung saan at anong klase, baka heat rash lang kung mainit dito, or insect bites, or contact dermatitis from something na ginamit mo. Para sure, better you see a doctor kasi need nila makita in person kung ano talaga at ibibigay nila yung tama na treatment, lalo na if it's spreading or hindi nawala.
