Aiyo, bisul at the back memang paling leceh sebab tak boleh jaga with your hands! Try to keep the area clean and dry, jangan pakai baju ketat, and kompres dengan air warm to help speed up the healing, tapi kalau dua-dua naik sekaligus and really sakit, better check with doctor cepat sikit in case kena antibiotics, okay? Semoga cepat habis ja, pantang duduk lama-lama mula!
